Add close_reason field to CLI schema and documentation

PR #551 persists close_reason, but the CLI documentation may not mention this field as part of the issue schema.

## Current State
- close_reason is now persisted in database
- `bd show --json` will return close_reason in JSON output
- Documentation may not reflect this new field

## What's Missing
- CLI reference documentation for close_reason field
- Schema documentation showing close_reason is a top-level issue field
- Example output showing close_reason in bd show --json
- bd close command documentation should mention close_reason parameter is optional

## Suggested Action
1. Update README.md or CLI reference docs to list close_reason as an issue field
2. Add example to bd close documentation
3. Update any type definitions or schema specs
4. Consider adding close_reason to verbose list output (bd list --verbose)


Daemon should be singleton and aggressively kill stale instances

Found 2 bd daemons running (PIDs 76868, 77515) during shutdown. The daemon should:

1. Be a singleton - only one instance per rig allowed
2. On startup, check for existing daemon and kill it before starting
3. Use a PID file or lock file to enforce this

Currently stale daemons can accumulate, causing confusion and resource waste.

**Investigation 2025-12-21:**

The singleton mechanism is already implemented and working correctly:

1. **daemon.lock** uses flock (exclusive non-blocking) to prevent duplicate daemons
2. **bd.sock.startlock** coordinates concurrent auto-starts via O_CREATE|O_EXCL
3. **Registry** tracks all daemons globally in ~/.beads/registry.json

Testing shows:
- Trying to start a second daemon gives: 'Error: daemon already running (PID X)'
- Multiple daemons for *different* rigs is expected/correct behavior

The original report ('Found 2 bd daemons running PIDs 76868, 77515') was likely:
1. Two daemons for different rigs (expected), OR
2. An edge case that's since been fixed

Consider closing as RESOLVED or clarifying the original scenario.

Schema: Add message type and new fields

Add to internal/storage/sqlite/schema.go and models:

New issue_type value:
- message

New optional fields on Issue struct:
- Sender string (who sent this)
- Ephemeral bool (can be bulk-deleted)
- RepliesTo string (issue ID for threading)
- RelatesTo []string (issue IDs for knowledge graph)
- Duplicates string (canonical issue ID)
- SupersededBy string (replacement issue ID)

Update:
- internal/storage/sqlite/schema.go - add columns
- internal/models/issue.go - add fields to struct
- internal/storage/sqlite/sqlite.go - CRUD operations
- Create migration from v0.30.1

Ensure backward compatibility - all new fields optional.


Add tests for import/export functionality

Import/export functions like ImportIssues, exportToJSONLWithStore, and AutoImportIfNewer have low coverage. These are critical for data integrity and multi-repo synchronization.


Implement backup functionality for reset

Add backup capability that can be used by reset command.

## Functionality
- Copy .beads/ to .beads-backup-{timestamp}/
- Timestamp format: YYYYMMDD-HHMMSS
- Preserve file permissions
- Return backup path for user feedback

## Location
`internal/reset/backup.go` - keep with reset package for now (YAGNI)

## Interface
```go
func CreateBackup(beadsDir string) (backupPath string, err error)
```

## Notes
- Simple recursive file copy, no compression needed
- Error if backup dir already exists (unlikely with timestamp)
- Backup directories SHOULD be gitignored
- Add `.beads-backup-*/` pattern to .beads/.gitignore template in doctor package
- Consider: ListBackups() for future `bd backup list` command (not for this PR)


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.


Phase 2.2: Switch bdt storage to TOON format

Currently bdt stores issues in JSONL format in issues.toon file. Phase 2.2 must implement actual TOON format storage - this is the fundamental goal of the bdtoon project.

## Current State (Phase 2.1)
- issues.toon stores JSONL (intermediate format)
- --toon flag allows output in TOON format for LLM consumption
- Problem: We're not actually using TOON as the fundamental storage format

## Required Work (Phase 2.2)
1. Switch issue file I/O to write TOON format instead of JSONL
   - Update cmd/bdt/storage.go to use EncodeTOON for writing
   - Update cmd/bdt/storage.go to decode TOON (currently decodes JSON)
   - Ensure round-trip: write TOON → read TOON → write TOON is byte-identical

2. Update command implementations
   - cmd/bdt/create.go: Write newly created issues to TOON format
   - cmd/bdt/list.go: Read issues from TOON format
   - cmd/bdt/show.go: Read from TOON format
   - cmd/bdt/import.go: Convert imported JSONL to TOON
   - cmd/bdt/export.go: Export TOON to JSONL (for bd compatibility)

3. Implement TOON parser that handles gotoon's encoder-only limitation
   - Since gotoon doesn't decode TOON, need custom TOON→JSON decoder
   - OR continue storing TOON but decoding via intermediate JSON conversion

4. Git merge driver optimization
   - TOON is line-oriented, better for 3-way merges than binary formats
   - Configure git merge driver for .toon files

5. Comprehensive testing
   - Round-trip tests: Issue → TOON → storage → read → Issue
   - Merge conflict resolution tests with TOON format
   - Large issue set performance tests

## Success Criteria
- issues.toon stores actual TOON format (not JSONL)
- bdt list reads from TOON file
- bdt create writes to TOON file
- Round-trip: create issue → list → show returns identical data
- All 65+ tests still passing
- Performance comparable to JSONL storage


Document sync.branch 'always dirty' working tree behavior

## Context

When sync.branch is configured, the .beads/issues.jsonl file in main's working tree is ALWAYS dirty. This is by design:

1. bd sync commits to beads-sync branch (via worktree)
2. bd sync copies JSONL to main's working tree (so CLI commands work)
3. This copy is NOT committed to main (to reduce commit noise)

Contributors who watch main branch history pushed for sync.branch to avoid constant beads commit noise. But users need to understand the trade-off.

## Documentation Needed

Update README.md sync.branch section with:

1. **Clear explanation** of why .beads/ is always dirty on main
2. **"Be Zen about it"** - this is expected, not a bug
3. **Workflow options:**
   - Accept dirty state, use `bd sync --merge` periodically to snapshot to main
   - Or disable sync.branch if clean working tree is more important
4. **Shell alias tip** to hide beads from git status:
   ```bash
   alias gs='git status -- ":!.beads/"'
   ```
5. **When to merge**: releases, milestones, or periodic snapshots

Fix TestImportBugIntegration deadlock in importer_test.go

Code health review found internal/importer/importer_test.go has TestImportBugIntegration skipped with:

TODO: Test hangs due to database deadlock - needs investigation

This indicates a potential unresolved concurrency issue in the importer. The test has been skipped for an unknown duration.

Fix: Investigate the deadlock, fix the underlying issue, and re-enable the test.


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


Consolidate maintenance commands into bd doctor --fix

Per rsnodgrass in GH#692:
> "The biggest improvement to beads from an ergonomics perspective would be to prune down commands. We have a lot of 'maintenance' commands that probably should just be folded into 'bd doctor --fix' automatically."

Current maintenance commands that could be consolidated:
- clean - Clean up temporary git merge artifacts
- cleanup - Delete closed issues and prune expired tombstones
- compact - Compact old closed issues
- detect-pollution - Detect and clean test issues
- migrate-* (5 commands) - Various migration utilities
- repair-deps - Fix orphaned dependency references
- validate - Database health checks

Proposal:
1. Make `bd doctor` the single entry point for health checks
2. Add `bd doctor --fix` to auto-fix common issues
3. Deprecate (but keep working) individual commands
4. Add `bd doctor --all` for comprehensive maintenance

This would reduce cognitive load for users - they just need to remember 'bd doctor'.

Note: This is higher impact but also higher risk - needs careful design to avoid breaking existing workflows.


Phase 2.3: TOON deletion tracking

Implement deletion tracking in TOON format.

## Overview
Phase 2.2 switched storage to TOON format. Phase 2.3 adds deletion tracking in TOON format for propagating deletions across clones.

## Required Work

### 2.3.1 Deletion Tracking (TOON Format)
- [ ] Implement deletions.toon file (tracking deleted issue records)
- [ ] Add DeleteTracker struct to record deleted issue IDs and metadata
- [ ] Update bdt delete command to record in deletions.toon
- [ ] Design deletion record format (ID, timestamp, reason, hash)
- [ ] Implement auto-prune of old deletion records (configurable TTL)

### 2.3.2 Sync Propagation
- [ ] Load deletions.toon during import
- [ ] Remove deleted issues from local database when imported from remote
- [ ] Handle edge cases (delete same issue in multiple clones)
- [ ] Deletion ordering and conflict resolution

### 2.3.3 Testing
- [ ] Unit tests for deletion tracking
- [ ] Integration tests for deletion propagation
- [ ] Multi-clone deletion scenarios
- [ ] TTL expiration tests

## Success Criteria
- deletions.toon stores deletion records in TOON format
- Deletions propagate across clones via git sync
- Old records auto-prune after TTL
- All 70+ tests still passing
- bdt delete command works seamlessly


Introduce slog for structured daemon logging.

## Current State
Daemon uses fmt.Fprintf for logging:
```go
fmt.Fprintf(os.Stderr, "Warning: failed to detect user role: %v\n", err)
fmt.Fprintf(logFile, "[%s] %s\n", time.Now().Format(time.RFC3339), msg)
```

This produces unstructured, hard-to-parse logs.

## Target State
Use Go 1.21+ slog for structured logging:
```go
slog.Warn("failed to detect user role", "error", err)
slog.Info("sync completed", "created", 5, "updated", 3, "duration_ms", 150)
```

## Implementation

### 1. Create logger setup (internal/daemon/logger.go)

```go
package daemon

import (
    "io"
    "log/slog"
    "os"
)

// SetupLogger configures the daemon logger.
// Returns a cleanup function to close the log file.
func SetupLogger(logPath string, jsonFormat bool, level slog.Level) (func(), error) {
    var w io.Writer = os.Stderr
    var cleanup func()

    if logPath \!= "" {
        f, err := os.OpenFile(logPath, os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0600)
        if err \!= nil {
            return nil, err
        }
        w = io.MultiWriter(os.Stderr, f)
        cleanup = func() { f.Close() }
    }

    var handler slog.Handler
    opts := &slog.HandlerOptions{Level: level}

    if jsonFormat {
        handler = slog.NewJSONHandler(w, opts)
    } else {
        handler = slog.NewTextHandler(w, opts)
    }

    slog.SetDefault(slog.New(handler))

    return cleanup, nil
}
```

### 2. Add log level flag

In cmd/bd/daemon.go:
```go
daemonCmd.Flags().String("log-level", "info", "Log level (debug, info, warn, error)")
daemonCmd.Flags().Bool("log-json", false, "Output logs in JSON format")
```

### 3. Replace fmt.Fprintf with slog calls

**Pattern 1: Simple messages**
```go
// Before
fmt.Fprintf(os.Stderr, "Starting daemon on %s\n", socketPath)

// After
slog.Info("starting daemon", "socket", socketPath)
```

**Pattern 2: Errors**
```go
// Before
fmt.Fprintf(os.Stderr, "Error: failed to connect: %v\n", err)

// After
slog.Error("failed to connect", "error", err)
```

**Pattern 3: Debug info**
```go
// Before
if debug {
    fmt.Fprintf(os.Stderr, "Received request: %s\n", method)
}

// After
slog.Debug("received request", "method", method)
```

**Pattern 4: Structured data**
```go
// Before
fmt.Fprintf(logFile, "Import: %d created, %d updated\n", created, updated)

// After
slog.Info("import completed",
    "created", created,
    "updated", updated,
    "unchanged", unchanged,
    "duration_ms", duration.Milliseconds())
```

### 4. Files to Update

| File | Changes |
|------|---------|
| cmd/bd/daemon.go | Add log flags, call SetupLogger |
| internal/daemon/server.go | Replace fmt with slog |
| internal/daemon/rpc_handler.go | Replace fmt with slog |
| internal/daemon/sync.go | Replace fmt with slog |
| internal/daemon/autoflush.go | Replace fmt with slog |
| internal/daemon/logger.go | New file |

### 5. Log output examples

**Text format (default):**
```
time=2025-12-23T12:30:00Z level=INFO msg="daemon started" socket=/tmp/bd.sock pid=12345
time=2025-12-23T12:30:01Z level=INFO msg="import completed" created=5 updated=3 duration_ms=150
time=2025-12-23T12:30:05Z level=WARN msg="sync branch diverged" local_ahead=2 remote_ahead=1
```

**JSON format (--log-json):**
```json
{"time":"2025-12-23T12:30:00Z","level":"INFO","msg":"daemon started","socket":"/tmp/bd.sock","pid":12345}
{"time":"2025-12-23T12:30:01Z","level":"INFO","msg":"import completed","created":5,"updated":3,"duration_ms":150}
```

## Migration Strategy

1. **Add logger.go** with SetupLogger
2. **Update daemon startup** to initialize slog
3. **Convert one file at a time** (start with server.go)
4. **Test after each file**
5. **Remove old logging code** once all converted

## Testing

```bash
# Start daemon with debug logging
bd daemon start --log-level debug

# Check logs
bd daemons logs . | head -20

# Test JSON output
bd daemon start --log-json --log-level debug
bd daemons logs . | jq .
```

## Success Criteria
- All daemon logging uses slog
- --log-level controls verbosity
- --log-json produces machine-parseable output
- Log entries have consistent structure
- No fmt.Fprintf to stderr in daemon code


HANDOFF: Molecule bonding - spawn done, bond next

## Context

Continuing work on bd-o5xe (Molecule bonding epic).

## Completed This Session

- bd-mh4w: Renamed bond to spawn in mol.go
- bd-rnnr: Added BondRef data model to types.go

## Now Unblocked

- internal/types/types.go

## Next Step

Start with bd-o91r. Run bd show bd-o5xe for context.


bd mol bond --pour should set Wisp=false

In mol_bond.go bondProtoMol(), opts.Wisp is hardcoded to true (line 392). This ignores the --pour flag. When user specifies --pour to make an issue persistent, the Wisp field should be false so the issue is not marked for bulk deletion.

Current behavior:
- --pour flag correctly selects regular storage (not wisp storage)
- But opts.Wisp=true means spawned issues are still marked for cleanup when closed

Expected behavior:
- --pour should set Wisp=false so persistent issues are not auto-cleaned

Comparison with mol_spawn.go (line 204):
  wisp := !pour  // Correctly respects --pour flag
  result, err := spawnMolecule(ctx, store, subgraph, vars, assignee, actor, wisp)

Fix: Pass pour flag to bondProtoMol and set opts.Wisp = !pour

Centralize error handling patterns in storage layer

80+ instances of inconsistent error handling across sqlite.go with mix of %w, %v, and no wrapping.

Location: internal/storage/sqlite/sqlite.go (throughout)

Problem:
- Some use fmt.Errorf("op failed: %w", err) - correct wrapping
- Some use fmt.Errorf("op failed: %v", err) - loses error chain
- Some return err directly - no context
- Hard to debug production issues
- Can't distinguish error types

Solution: Create internal/storage/sqlite/errors.go:
- Define sentinel errors (ErrNotFound, ErrInvalidID, etc.)
- Create wrapDBError(op string, err error) helper
- Convert sql.ErrNoRows to ErrNotFound
- Always wrap with operation context

Impact: Lost error context; inconsistent messages; hard to debug

Effort: 5-7 hours


Document BEADS_DIR pattern for multi-agent workspaces (Gas Town)

Gas Town and similar multi-agent systems need to configure separate beads databases per workspace/rig, distinct from any project-level beads.

## Use Case

In Gas Town:
- Each 'rig' (managed project) has multiple agents (polecats, refinery, witness)
- All agents in a rig should share a single beads database at the rig level
- This should be separate from any .beads/ the project itself uses
- The BEADS_DIR env var enables this

## Documentation Needed

1. Add a section to docs explaining BEADS_DIR for multi-agent setups
2. Example: setting BEADS_DIR in agent startup scripts/hooks
3. Clarify interaction with project-level .beads/ (BEADS_DIR takes precedence)

## Current Support

Already implemented in internal/beads/beads.go:FindDatabasePath():
- BEADS_DIR env var is checked first (preferred)
- BEADS_DB env var still supported (deprecated)
- Falls back to .beads/ search in tree

Just needs documentation for the multi-agent workspace pattern.

Test suite hangs/never finishes

Running 'go test ./... -count=1' hangs indefinitely. The full test suite never completes, making it difficult to verify changes. Need to investigate which tests are hanging and fix or add timeouts.
