CHANGES:
1. Merge logic (internal/merge/merge.go):
- Added mergeStatus() enforcing closed ALWAYS wins over open
- Fixed closed_at handling: only set when status='closed'
- Changed deletion handling: deletion ALWAYS wins over modification
2. Deletion tracking (cmd/bd/snapshot_manager.go):
- Updated ComputeAcceptedDeletions to accept all merge deletions
- Removed "unchanged locally" check (deletion wins regardless)
3. FK constraint helper (internal/storage/sqlite/util.go):
- Added IsForeignKeyConstraintError() for bd-koab
- Detects FK violations for graceful import handling
TESTS UPDATED:
- TestMergeStatus: comprehensive status merge tests
- TestIsForeignKeyConstraintError: FK constraint detection
- bd-pq5k test: validates no invalid state (status=open with closed_at)
- Deletion tests: reflect new deletion-wins behavior
- All tests pass ✓
This ensures issues never get stuck in invalid states and prevents
the insane situation where issues never die!
