Code review and fixes:
- Increased scanner buffer to 2MB for large JSON lines
- Added line numbers and snippets to parse error messages
- Made non-SQLite fallback conservative (skip import to prevent data loss)
- Improved collision warnings (concise, show first 10 IDs)
- Removed unused autoImportWithoutCollisionDetection function
Status/closed_at invariant enforcement:
- Auto-import now enforces invariant on all creates/updates
- Fixed CreateIssue to respect closed_at field (was ignoring it)
- Closed issues without closed_at get timestamp set automatically
Integration tests:
- TestAutoImportWithCollision: verifies local changes preserved
- TestAutoImportNoCollision: happy path with new issues
- TestAutoImportClosedAtInvariant: enforces invariant

Implements bd-42: Add test coverage for auto-flush feature
Created cmd/bd/main_test.go with 11 comprehensive test functions:
- TestAutoFlushDirtyMarking: Verifies markDirtyAndScheduleFlush() marks DB as dirty
- TestAutoFlushDisabled: Tests --no-auto-flush flag disables feature
- TestAutoFlushDebounce: Tests rapid operations result in single flush
- TestAutoFlushClearState: Tests clearAutoFlushState() resets state
- TestAutoFlushOnExit: Tests flush happens on program exit
- TestAutoFlushConcurrency: Tests concurrent operations don't cause races
- TestAutoFlushStoreInactive: Tests flush skips when store is inactive
- TestAutoFlushJSONLContent: Tests flushed JSONL has correct content
- TestAutoFlushErrorHandling: Tests error scenarios (permissions, etc.)
- TestAutoImportIfNewer: Tests auto-import when JSONL is newer than DB
- TestAutoImportDisabled: Tests --no-auto-import flag disables auto-import
Coverage results:
- markDirtyAndScheduleFlush: 100%
- clearAutoFlushState: 100%
- flushToJSONL: 67.6%
- autoImportIfNewer: 66.1% (up from 0%)
All tests pass. Auto-flush feature is now thoroughly tested.
