CHANGES:
- Reduced from 15 DB setups to 4 shared DBs
- TestValidatePreExportSuite: 1 shared DB, 5 subtests
- TestValidatePostImport: No DB needed, kept as-is
- TestCountDBIssuesSuite: 1 shared DB, 1 subtest
- TestHasJSONLChangedSuite: 1 shared DB, 7 subtests (with unique keySuffixes)
- TestComputeJSONLHash: No DB needed, kept as-is
- TestCheckOrphanedDepsSuite: 1 shared DB, 2 subtests
PERFORMANCE:
- Before: 0.455s avg (15 DB setups)
- After: 0.373s avg (4 DB setups)
- Speedup: 1.22x (18% faster)
KEY LEARNINGS:
- Used unique keySuffix values for hasJSONLChanged subtests to avoid metadata pollution
- Metadata keys like last_import_hash are shared across subtests unless keySuffix is used
- TestValidatePostImport and TestComputeJSONLHash do not need DB at all
PATTERN:
Following create_test.go and dep_test.go pattern with shared DB setup
Part of Phase 2 test suite optimization (bd-1rh follow-up)

This commit addresses critical code review findings from bd-dvd and bd-ymj fixes:
## Completed Tasks
### bd-ar2.1: Extract duplicated metadata update code
- Created `updateExportMetadata()` helper function
- Eliminated 22-line duplication between createExportFunc and createSyncFunc
- Single source of truth for metadata updates
### bd-ar2.2: Add multi-repo support to export metadata updates
- Added per-repo metadata key tracking with keySuffix parameter
- Both export and sync functions now update metadata for all repos
### bd-ar2.3: Fix tests to use actual daemon functions
- TestExportUpdatesMetadata now calls updateExportMetadata() directly
- Added TestUpdateExportMetadataMultiRepo() for multi-repo testing
- Fixed export_mtime_test.go tests to call updateExportMetadata()
### bd-ar2.9: Fix variable shadowing in GetNextChildID
- Changed `err` to `resurrectErr` to avoid shadowing
- Improves code clarity and passes linter checks
### bd-ar2.10: Fix hasJSONLChanged to support per-repo keys
- Updated hasJSONLChanged() to accept keySuffix parameter
- Reads metadata with correct per-repo keys
- All callers updated (validatePreExport, daemon import, sync command)
### bd-ar2.11: Use stable repo identifiers instead of paths
- Added getRepoKeyForPath() helper function
- Uses stable identifiers like ".", "../frontend" instead of absolute paths
- Metadata keys now portable across machines and clones
- Prevents orphaned metadata when repos are moved
## Files Changed
- cmd/bd/daemon_sync.go: Helper functions, metadata updates
- cmd/bd/integrity.go: hasJSONLChanged() with keySuffix support
- cmd/bd/sync.go: Updated to use getRepoKeyForPath()
- cmd/bd/*_test.go: Tests updated for new signatures
- internal/storage/sqlite/hash_ids.go: Fixed variable shadowing
## Testing
All export, sync, and integrity tests pass.

Replace mtime-based staleness detection with content-based (SHA256 hash) to prevent
git operations from resurrecting deleted issues.
**Problem:**
Auto-import used file modification time to detect if JSONL was "newer" than database.
Git operations (checkout, merge, pull) restore old files with recent mtimes, causing
auto-import to load stale data over current database state, resurrecting deleted issues.
**Solution:**
- Added computeJSONLHash() to compute SHA256 of JSONL content
- Added hasJSONLChanged() with two-tier check:
1. Fast-path: Check mtime first (99% of checks are instant)
2. Slow-path: Compute hash only if mtime changed (catches git operations)
- Store metadata: last_import_hash, last_import_mtime, last_import_time
- Updated auto-import in daemon_sync.go to use content-based check
- Updated validatePreExport to use content-based check (bd-xwo)
- Graceful degradation: metadata failures are non-fatal warnings
**Changes:**
- cmd/bd/integrity.go: Add computeJSONLHash(), hasJSONLChanged()
- cmd/bd/integrity_test.go: Add comprehensive tests for new functions
- cmd/bd/import.go: Update metadata after import
- cmd/bd/sync.go: Use hasJSONLChanged() instead of isJSONLNewer()
- cmd/bd/daemon_sync.go: Use hasJSONLChanged() in auto-import
**Testing:**
- Unit tests pass (TestHasJSONLChanged with 7 scenarios)
- Integration test passes (test_bd_khnb_fix.sh)
- Verified git resurrection scenario prevented

- Add JSONL timestamp check in validatePreExport
- Refuse export if JSONL is newer than database
- Force daemon to import before exporting when JSONL updated
- Add test case for JSONL-newer-than-DB scenario
- Fixes bd-89e2
- Added validatePreExport to prevent data loss
- Added checkDuplicateIDs to detect corruption
- Added checkOrphanedDeps to find orphaned dependencies (both sides)
- Added validatePostImport to ensure imports don't lose data
- CRITICAL FIX: Removed post-pull export that clobbered fresh JSONL
- Conservative checks when JSONL is unreadable
- Efficient COUNT(*) SQL path instead of loading all issues
- Comprehensive test coverage including edge cases
