Refactor duplicate JSONL-from-git parsing code

Both readFirstIssueFromGit() in init.go and importFromGit() in autoimport.go have similar code patterns for:
1. Running git show <ref>:<path>
2. Scanning the output with bufio.Scanner
3. Parsing JSON lines

Could be refactored to share a helper like:
- readJSONLFromGit(gitRef, path string) ([]byte, error)
- Or a streaming version: streamJSONLFromGit(gitRef, path string) (io.Reader, error)

Files:
- cmd/bd/autoimport.go:225-256 (importFromGit)
- cmd/bd/init.go:1212-1243 (readFirstIssueFromGit)

Priority is low since code duplication is minimal and both functions work correctly.


bd sync fails with orphaned issues and duplicate ID conflict

After fixing the deleted_at TEXT column scanning bug (commit 18b1eb2), bd sync still fails with two issues:

1. Orphan Detection Warning: 12 orphaned child issues whose parents no longer exist (bd-cb64c226.* and bd-cbed9619.*)

2. Import Failure: UNIQUE constraint failed for bd-360 - this tombstone exists in both DB and JSONL

Error: "Import failed: error creating depth-0 issues: bulk insert issues: failed to insert issue bd-360: sqlite3: constraint failed: UNIQUE constraint failed: issues.id"

Fix options:
- Delete orphaned child issues with bd delete
- Resolve bd-360 duplicate (in deletions.jsonl vs tombstone in DB)
- Reset sync branch: git branch -f beads-sync main && git push --force-with-lease origin beads-sync

Fixed tombstone constraint violation bug. When deleting closed issues, the CHECK constraint (status = 'closed') = (closed_at IS NOT NULL) was violated because CreateTombstone didn't clear closed_at. Fix: set closed_at = NULL in tombstone creation SQL.

The sync data corruption (orphaned issues in beads-sync branch) requires manual cleanup: reset sync branch with 'git branch -f beads-sync main && git push --force-with-lease origin beads-sync'


Add bd reset command for clean slate restart

Implement a `bd reset` command to reset beads to a clean starting state.

## Context
GitHub issue #479 - users sometimes get beads into an invalid state after updates, and there's no clean way to start fresh. The git backup/restore mechanism that protects against accidental deletion also makes it hard to intentionally reset.

## Design

### Command Interface
```
bd reset [--hard] [--force] [--backup] [--dry-run] [--no-init]
```

| Flag | Effect |
|------|--------|
| `--hard` | Also remove from git index and commit |
| `--force` | Skip confirmation prompt |
| `--backup` | Create `.beads-backup-{timestamp}/` first |
| `--dry-run` | Preview what would happen |
| `--no-init` | Don't re-initialize after clearing |

### Reset Levels
1. **Soft Reset (default)** - Kill daemons, clear .beads/, re-init. Git history unchanged.
2. **Hard Reset (`--hard`)** - Also git rm and commit the removal, then commit fresh state.

### Implementation Flow
1. Validate .beads/ exists
2. If not --force: show impact summary, prompt confirmation
3. If --backup: copy .beads/ to .beads-backup-{timestamp}/
4. Kill daemons
5. If --hard: git rm + commit
6. rm -rf .beads/*
7. If not --no-init: bd init (and git add+commit if --hard)
8. Print summary

### Safety Mechanisms
- Confirmation prompt (skip with --force)
- Impact summary (issue/tombstone counts)
- Backup option
- Dry-run preview
- Git dirty check warning

### Code Structure
- `cmd/bd/reset.go` - CLI command
- `internal/reset/` - Core logic package


bd validate - Comprehensive health check

Run all validation checks in one command.

Checks:
- Duplicates
- Orphaned dependencies
- Test pollution
- Git conflicts

Supports --fix-all for auto-repair.

Depends on bd-cbed9619.1, bd-0dcea000, bd-31aab707, bd-9826b69a.

Files: cmd/bd/validate.go (new)


Re: Thread Test 2

Great! Thread is working well.


Remove unreachable RPC methods

Several RPC server and client methods are unreachable and should be removed:

Server methods (internal/rpc/server.go):
- `Server.GetLastImportTime` (line 2116)
- `Server.SetLastImportTime` (line 2123)
- `Server.findJSONLPath` (line 2255)

Client methods (internal/rpc/client.go):
- `Client.Import` (line 311) - RPC import not used (daemon uses autoimport)

Evidence:
```bash
go run golang.org/x/tools/cmd/deadcode@latest -test ./...
```

Impact: Removes ~80 LOC of unused RPC code


Monitor npm publish

Watch the npm publish action:
https://github.com/steveyegge/beads/actions/workflows/npm-publish.yml

Verify at: https://www.npmjs.com/package/@anthropics/claude-code-beads-plugin/v/0.30.4

Check:
```bash
npm view @anthropics/claude-code-beads-plugin@0.30.4 version
```

```verify
npm view @anthropics/claude-code-beads-plugin@0.30.4 version 2>/dev/null | grep -q '0.30.4'
```


Implement core reset package (internal/reset)

Create the core reset logic in internal/reset/ package.

## Responsibilities
- ResetOptions struct with all flag options
- CountImpact() - count issues/tombstones that will be deleted
- ValidateState() - check .beads/ exists, check git dirty state
- ExecuteReset() - main reset logic (without CLI concerns)
- Integrate with daemon killall

## Interface Design
```go
type ResetOptions struct {
    Hard      bool   // Include git operations (git rm, commit)
    Backup    bool   // Create backup before reset
    DryRun    bool   // Preview only, don't execute
    SkipInit  bool   // Don't re-initialize after reset
}

type ResetResult struct {
    IssuesDeleted     int
    TombstonesDeleted int
    BackupPath        string  // if backup was created
    DaemonsKilled     int
}

type ImpactSummary struct {
    IssueCount      int
    OpenCount       int
    ClosedCount     int
    TombstoneCount  int
    HasUncommitted  bool  // git dirty state
}

func Reset(opts ResetOptions) (*ResetResult, error)
func CountImpact() (*ImpactSummary, error)
func ValidateState() error
```

## IMPORTANT: CLI vs Core Separation
- `Force` (skip confirmation) is NOT in ResetOptions - that's a CLI concern
- Core always executes when called; CLI decides whether to prompt first
- Keep CLI-agnostic: no prompts, no colored output, no user interaction
- Return errors for CLI to handle with user-friendly messages
- Unit testable in isolation

## Dependencies
- Uses daemon.KillAllDaemons() from internal/daemon/
- Calls bd init logic after reset (unless SkipInit)


Implement CLI command (cmd/bd/reset.go)

Wire up the reset command with Cobra CLI.

## Responsibilities
- Define command and all flags
- User confirmation prompt (unless --force)
- Display impact summary before confirmation
- Colored output and progress indicators
- Call core reset package
- Handle errors with user-friendly messages
- Register command with rootCmd in init()

## Flags
```go
--hard       bool   "Also remove from git and commit"
--force      bool   "Skip confirmation prompt"
--backup     bool   "Create backup before reset"
--dry-run    bool   "Preview what would happen"
--skip-init  bool   "Do not re-initialize after reset"
--verbose    bool   "Show detailed progress output"
```

## Output Format
```
⚠  This will reset beads to a clean state.

Will be deleted:
  • 47 issues (23 open, 24 closed)
  • 12 tombstones

Continue? [y/N] y

→ Stopping daemons... ✓
→ Removing .beads/... ✓
→ Initializing fresh... ✓

✓ Reset complete. Run 'bd onboard' to set up hooks.
```

## Implementation Notes
- Confirmation logic lives HERE, not in core package
- Use color package (github.com/fatih/color) for output
- Follow patterns from other commands (init.go, doctor.go)
- Add to rootCmd in init() function

## File Location
`cmd/bd/reset.go`


Add sync resilience guardrails for forced pushes and prefix mismatches

Beads can get into unrecoverable sync states when remote forces pushes occur (e.g., rebases) combined with prefix mismatches from multi-worker scenarios. Add detection, prevention, and auto-recovery features to handle this gracefully.

Cleanup: --ephemeral flag

Update bd cleanup to handle ephemeral issues.

New flag:
- bd cleanup --ephemeral - deletes all CLOSED issues with ephemeral=true

Behavior:
- Only deletes if status=closed AND ephemeral=true
- Respects --dry-run flag
- Reports count of deleted ephemeral issues

This allows swarm cleanup to remove transient messages without affecting permanent issues.


No logging/debugging for tombstone resurrection events

Per the design document bd-zvg Open Question 1: Should resurrection log a warning? Recommendation was Yes. Currently, when an expired tombstone loses to a live issue (resurrection), there is no logging or debugging output. This makes it hard to understand why an issue reappeared. Recommendation: Add optional debug logging when resurrection occurs, e.g., Issue bd-abc resurrected (tombstone expired). Files: internal/merge/merge.go:359-366, 371-378, 400-405, 410-415


Add test files for internal/storage

The internal/storage package has no test files at all. This package provides the storage interface abstraction.

Current coverage: N/A (no test files)
Target: Add basic interface tests


Consider using types.Status in merge package for type safety

The merge package uses string for status comparison (e.g., result.Status == closed, issue.Status == StatusTombstone). The types package defines Status as a type alias with validation. While the merge package needs its own Issue struct for JSONL flexibility, it could import and use types.Status for constants to get compile-time type checking. Current code: if left == closed || right == closed. Could be: if left == string(types.StatusClosed). This is low priority since string comparison works correctly. Files: internal/merge/merge.go:44, 488, 501-521


Test issue 2


bd doctor should recommend bd prime migration for existing repos

bd doctor should detect old beads integration patterns and recommend migrating to bd prime approach.

## Current behavior
- bd doctor checks if Claude hooks are installed globally
- Doesn't check project-level integration (AGENTS.md, CLAUDE.md)
- Doesn't recommend migration for repos using old patterns

## Desired behavior
bd doctor should detect and suggest:

1. **Old slash command pattern detected**
   - Check for /beads:* references in AGENTS.md, CLAUDE.md
   - Suggest: These slash commands are deprecated, use bd prime hooks instead

2. **No agent documentation**
   - Check if AGENTS.md or CLAUDE.md exists
   - Suggest: Run 'bd onboard' or 'bd setup claude' to document workflow

3. **Old MCP-only pattern**
   - Check for instructions to use MCP tools but no bd prime hooks
   - Suggest: Add bd prime hooks for better token efficiency

4. **Migration path**
   - Show: 'Run bd setup claude to add SessionStart/PreCompact hooks'
   - Show: 'Update AGENTS.md to reference bd prime instead of slash commands'

## Example output

⚠ Warning: Old beads integration detected in CLAUDE.md
  Found: /beads:* slash command references (deprecated)
  Recommend: Migrate to bd prime hooks for better token efficiency
  Fix: Run 'bd setup claude' and update CLAUDE.md

💡 Tip: bd prime + hooks reduces token usage by 80-99% vs slash commands
  MCP mode: ~50 tokens vs ~10.5k for full MCP scan
  CLI mode: ~1-2k tokens with automatic context recovery

## Benefits
- Helps existing repos adopt new best practices
- Clear migration path for users
- Better token efficiency messaging


Auto-recovery mode (bd sync --auto-recover)

Add bd sync --auto-recover flag that: detects problematic sync state, backs up .beads/issues.db with timestamp, rebuilds DB from JSONL atomically, verifies consistency, reports what was fixed. Provides safety valve when sync integrity fails.


Graph Link: replies_to for conversation threading

Implement replies_to link type for message threading.

New command:
- bd mail reply <id> -m 'Response' creates a message with replies_to set

Query support:
- bd show <id> --thread shows full conversation thread
- Thread traversal in storage layer

Storage:
- replies_to column in issues table
- Index for efficient thread queries

This enables Reddit-style nested threads where messages reply to other messages.


getLocalSyncBranch silently ignores YAML parse errors

In autoimport.go:170-172, YAML parsing errors are silently ignored. If a user has malformed YAML in config.yaml, sync-branch will just silently be empty with no feedback.

Recommendation: Add debug logging since this function is only called during auto-import, and debugging silent failures is painful.

Add: debug.Logf("Warning: failed to parse config.yaml: %v", err)


Improve test coverage for internal/syncbranch (33.0% → 70%)

The syncbranch package has only 33.0% test coverage. This package handles git sync operations and is critical for data integrity.

Current coverage: 33.0%
Target coverage: 70%


GH#409: bd init uses issues.jsonl but docs say beads.jsonl

bd init creates config referencing issues.jsonl but README/docs reference beads.jsonl as canonical. Standardize naming. See GitHub issue #409.


Make DetectCollisions read-only (separate detection from modification)

**Summary:** The project restructured the collision detection process in the database to separate read-only detection from state modification, eliminating race conditions and improving system reliability. This was achieved by introducing a two-phase approach: first detecting potential collisions, then applying resolution separately.

**Key Decisions:**
- Create read-only DetectCollisions method
- Add RenameDetail to track potential issue renames
- Implement atomic ApplyCollisionResolution function
- Separate detection logic from database modification

**Resolution:** The refactoring creates a more robust, composable collision handling mechanism that prevents partial failures and maintains database consistency during complex issue import scenarios.


bd find-duplicates - AI-powered duplicate detection

Find semantically duplicate issues.

Approaches:
1. Mechanical: Exact title/description matching
2. Embeddings: Cosine similarity (cheap, scalable)
3. AI: LLM-based semantic comparison (expensive, accurate)

Uses embeddings by default for >100 issues.

Files: cmd/bd/find_duplicates.go (new)


bd init should stop running daemon to avoid stale cache

When running bd init, any running daemon continues with stale cached data, causing bd stats and other commands to show old counts.

Repro:
1. Have daemon running with 788 issues cached
2. Clean JSONL to 128 issues, delete db, run bd init
3. bd stats still shows 788 (daemon cache)
4. Must manually run bd daemon --stop

Fix: bd init should automatically stop any running daemon before reinitializing.


Deleted issues resurrect during bd sync (tombstones not propagating)

## Problem

When issues are deleted with bd delete --force, they get deleted from the local DB but resurrect during the next bd sync.

## Reproduction

1. Observe orphan warnings (bd-cb64c226.*, bd-cbed9619.*)
2. Delete them: bd delete bd-cb64c226.1 ... --force
3. Run bd sync
4. Orphan warnings reappear - issues were resurrected!

## Root Cause Hypothesis

The sync branch workflow (beads-sync) has the old state before deletions. When bd sync pulls from beads-sync and copies JSONL to main, the deleted issues are re-imported.

Tombstones may not be properly:
1. Written to beads-sync during export
2. Propagated during pull/merge
3. Honored during import

## Related

- bd-7b7h: chicken-and-egg sync.branch bug (same workflow)
- bd-ncwo: ID-based fallback matching to prevent ghost resurrection

## Files to Investigate

- cmd/bd/sync.go (export/import flow)
- internal/syncbranch/worktree.go (PullFromSyncBranch, copyJSONLToMainRepo)
- internal/importer/ (tombstone handling)


Improve bd doctor output formatting for better readability

The current bd doctor output is a wall of text that's hard to process. Consider improvements like:
- Grouping related checks into collapsible sections
- Using color/bold for section headers
- Showing only failures/warnings by default with --verbose for full output
- Better visual hierarchy between major sections
- Summary line at top (e.g., '24 checks passed, 0 warnings, 0 errors')


Add bd daemon --stop-all command to kill all daemon processes

Currently there's no easy way to stop all running bd daemon processes. Users must resort to pkill -f 'bd daemon' or similar shell commands.

Add a --stop-all flag to bd daemon that:
1. Finds all running bd daemon processes (not just the current repo's daemon)
2. Gracefully stops them all
3. Reports how many were stopped

This is useful when:
- Multiple daemons are running and causing race conditions
- User wants a clean slate before running bd sync
- Debugging daemon-related issues


wish: a 'continue' or similar cmd/flag which means alter last issue

so many time I create an issue and then have another thought: 'oh, before I did X and it crashed there was ZZZ happening' or 'actually that is P4 not P2'. It would be nice if when `bd {cmd}` is used without a {title} or {id} it just adds or updates the most recently touched issue.


Improve test coverage for internal/beads (48.1% → 70%)

The beads package is a core package with 48.1% coverage. As the primary package for issue management, it should have at least 70% coverage.

Current coverage: 48.1%
Target coverage: 70%


Verify MCP Server Compatibility

Ensure MCP server works with cache-free daemon


Code Review: PR #481 - Context Engineering Optimizations

Comprehensive code review of the merged context engineering PR (PR #481) that reduces MCP context usage by 80-90%.

## Summary
The PR successfully implements lazy tool schema loading and minimal issue models to reduce context window usage. Overall implementation is solid and well-tested.

## Positive Findings
✅ Well-designed models (IssueMinimal, CompactedResult)
✅ Comprehensive test coverage (28 tests, all passing)
✅ Clear documentation and comments
✅ Backward compatibility preserved (show() still returns full Issue)
✅ Sensible defaults (COMPACTION_THRESHOLD=20, PREVIEW_COUNT=5)
✅ Tool catalog complete with all 15 tools documented

## Issues Identified
See linked issues for specific followup tasks.

## Context Engineering Architecture
- discover_tools(): List tool names only (~500 bytes vs ~15KB)
- get_tool_info(name): Get specific tool details on-demand
- IssueMinimal: Lightweight model for list views (~80 bytes vs ~400 bytes)
- CompactedResult: Auto-compacts results with >20 issues
- _to_minimal(): Conversion function (efficient, no N+1 issues)


Investigate charmbracelet-based TUI for beads

Now that we've merged the create-form command (PR #603) which uses charmbracelet/huh, investigate whether beads should have a more comprehensive TUI.

Considerations:
- Should this be in core or a separate binary (bd-tui)?
- What functionality would benefit from a TUI? (list view, issue details, search, bulk operations)
- Plugin/extension architecture vs build tags vs separate binary
- Dependency cost vs user experience tradeoff
- Target audience: humans who want interactive workflows vs CLI/scripting users

Related: PR #603 added charmbracelet/huh dependency for create-form command.


Add --hard flag to bd cleanup to permanently cull tombstones before cutoff date

Currently tombstones persist for 30 days before cleanup prunes them. Need an official way to force-cull tombstones earlier than the default TTL, for scenarios like cleaning house after extended absence where resurrection from old clones is not a concern. Proposed: bd cleanup --hard --older-than N to bypass the 30-day tombstone TTL.


Create version-bump template as native Beads

Migrate the version-bump workflow from YAML to a native Beads template:

1. Create epic with template label: Release {{version}}
2. Create child tasks for each step (update version files, changelog, commit, push, publish)
3. Set up dependencies between tasks
4. Add verification commands in task descriptions

This serves as both migration and validation of the new system.


Add 0.30.4 to info.go release notes

Update cmd/bd/info.go versionChanges map with release notes for 0.30.4.
Include any workflow-impacting changes for --whats-new output.


GH#509: bd doesn't find .beads when running from nested worktrees

When worktrees are nested under main repo (.worktrees/feature/), bd stops at worktree git root instead of continuing to find .beads in parent. See GitHub issue #509 for detailed fix suggestion.


Update .claude-plugin/plugin.json to 0.30.4

Update version field in .claude-plugin/plugin.json:
```json
"version": "0.30.4"
```

```verify
jq -e '.version == "0.30.4"' .claude-plugin/plugin.json
```


Test body-file

This is a test description from a file.

It has multiple lines.


Add comprehensive filters to bd export

Enhance bd export with filtering options for selective exports.

**Currently only has:**
- --status

**Add filters:**
- --label, --label-any
- --assignee
- --type
- --priority, --priority-min, --priority-max
- --created-after, --created-before
- --updated-after, --updated-before

**Use case:**
- Export only open issues: bd export --status open
- Export high-priority bugs: bd export --type bug --priority-max 1
- Export recent issues: bd export --created-after 2025-01-01

**Files to modify:**
- cmd/bd/export.go
- Reuse filter logic from list.go

Graph Link: supersedes for version chains

Implement supersedes link type for version tracking.

New command:
- bd supersede <id> --with <new> - marks id as superseded by new
- Auto-closes the superseded issue

Query support:
- bd show <id> shows 'Superseded by: <new>'
- bd show <new> shows 'Supersedes: <id>'
- bd list --superseded shows version chains

Storage:
- superseded_by column pointing to replacement issue

Useful for design docs, specs, and evolving artifacts.

GH#403: bd doctor --fix circular error message

bd doctor --fix suggests running bd doctor --fix for deletions manifest issue. Fix to provide actual resolution. See GitHub issue #403.


Remove unreachable utility functions

Several small utility functions are unreachable:

Files to clean:
1. `internal/storage/sqlite/hash.go` - `computeIssueContentHash` (line 17)
   - Check if entire file can be deleted if only contains this function

2. `internal/config/config.go` - `FileUsed` (line 151)
   - Delete unused config helper

3. `cmd/bd/git_sync_test.go` - `verifyIssueOpen` (line 300)
   - Delete dead test helper

4. `internal/compact/haiku.go` - `HaikuClient.SummarizeTier2` (line 81)
   - Tier 2 summarization not implemented
   - Options: implement feature OR delete method

Impact: Removes 50-100 LOC depending on decisions


Sync branch integrity guards

Track sync branch parent commit. If sync branch was force-pushed, warn user and require confirmation before proceeding. Add option to reset to remote if user accepts rebase. Prevents silent corruption from forced pushes.


Code Review: PR #551 - Persist close_reason to issues table

Code review of PR #551 which fixes close_reason persistence bug.

## Summary
The PR correctly fixes a bug where close_reason was only stored in the events table, not in the issues.close_reason column. This caused `bd show --json` to return empty close_reason.

## What Was Fixed
- ✅ CloseIssue now updates both close_reason and closed_at
- ✅ ReOpenIssue clears both close_reason and closed_at
- ✅ Comprehensive tests added for both storage and CLI layers
- ✅ Clear documentation in queries.go about dual storage strategy

## Quality Assessment
✅ Tests cover both storage layer and CLI JSON output
✅ Handles reopen case (clearing close_reason)
✅ Good comments explaining dual-storage design
✅ No known issues

## Potential Followups
See linked issues for suggestions.


Fix G104 errors unhandled in internal/storage/sqlite/queries.go:1181

Linting issue: G104: Errors unhandled (gosec) at internal/storage/sqlite/queries.go:1181:4. Error: rows.Close()


bd delete --from-file should add deleted issues to deletions manifest

When using bd delete --from-file to bulk delete issues, the deleted issue IDs are not being added to the deletions.jsonl manifest.

This causes those issues to be resurrected during bd sync when git history scanning finds them in old commits.

Expected: All deleted issues should be added to deletions.jsonl so they wont be reimported from git history.

Workaround: Manually add deletion records to deletions.jsonl.


Add close_reason to JSONL export format documentation

PR #551 now persists close_reason to the database, but there's a question about whether this field should be exported to JSONL format.

## Current State
- close_reason is stored in issues.close_reason column
- close_reason is also stored in events table (audit trail)
- The JSONL export format may or may not include close_reason

## Questions
1. Should close_reason be exported to JSONL format?
2. If yes, where should it go (root level or nested in events)?
3. Should there be any special handling to avoid duplication?
4. How should close_reason be handled during JSONL import?

## Why This Matters
- JSONL is the git-friendly sync format
- Other beads instances import from JSONL
- close_reason is meaningful data that should be preserved across clones

## Suggested Action
- Check if close_reason is currently exported in JSONL
- If not, add it to the export schema
- Document the field in JSONL format spec
- Add tests for round-trip (export -> import -> verify close_reason)


Ghost resurrection: remote status:closed wins during git merge

During bd sync, the 3-way git merge sometimes keeps remote's status:closed instead of local's status:tombstone. This causes ghost issues to resurrect even when tombstones exist.

Root cause: Git 3-way merge doesn't understand tombstone semantics. If base had closed, local changed to tombstone, and remote has closed, git might keep remote's version.

The early tombstone check in importer.go only prevents CREATION when tombstones exist in DB. But if applyDeletionsFromMerge hard-deletes the tombstones before import runs (because they're not in the merged result), the check doesn't help.

Potential fixes:
1. Make tombstones 'win' in the beads merge driver (internal/merge/merge.go)
2. Don't hard-delete tombstones in applyDeletionsFromMerge if they're in the DB
3. Export tombstones to a separate file that's not subject to merge

Ghost issues: bd-cb64c226.*, bd-cbed9619.*


Time-dependent tests may be flaky near TTL boundary

Several tombstone merge tests use time.Now() to create test data: time.Now().Add(-24 * time.Hour), time.Now().Add(-60 * 24 * time.Hour), etc. While these work reliably in practice (24h vs 30d TTL has large margin), they could theoretically be flaky if: 1) Tests run slowly, 2) System clock changes during test, 3) TTL constants change. Recommendation: Consider using a fixed reference time or time injection for deterministic tests. Lower priority since current margin is large. Files: internal/merge/merge_test.go:1337-1338, 1352-1353, 1548-1549, 1590-1591


Remove Cache-Related Tests

Delete or update tests that assume multi-repo caching


Fix daemon/direct mode inconsistency in relate and duplicate commands

The relate.go and duplicate.go commands have inconsistent daemon/direct mode handling:

When daemonClient is connected, they resolve IDs via RPC but then perform updates directly via store.UpdateIssue(), bypassing the daemon.

Affected locations:
- relate.go:125-139 (runRelate update)
- relate.go:235-246 (runUnrelate update)
- duplicate.go:120 (runDuplicate update)
- duplicate.go:207 (runSupersede update)

Should either use RPC for updates when daemon is running, or document why direct access is intentional.


Improve CheckStaleness error handling

## Problem

CheckStaleness returns 'false' (not stale) for multiple error conditions instead of returning errors. This masks problems.

**Location:** internal/autoimport/autoimport.go:253-285

## Edge Cases That Return False

1. **Invalid last_import_time format** (line 259-262)
2. **No JSONL file found** (line 267-277)
3. **JSONL stat fails** (line 279-282)

## Fix

Return errors for abnormal conditions:

```go
lastImportTime, err := time.Parse(time.RFC3339, lastImportStr)
if err != nil {
    return false, fmt.Errorf("corrupted last_import_time: %w", err)
}

if jsonlPath == "" {
    return false, fmt.Errorf("no JSONL file found")
}

stat, err := os.Stat(jsonlPath)
if err != nil {
    return false, fmt.Errorf("cannot stat JSONL: %w", err)
}
```

## Impact
Medium - edge cases are rare but should be handled

## Effort
30 minutes - requires updating callers in RPC server
