handle deletion when SQLite is not available. This fixes the error

Adds tests for the daemon-side RPC delete handler (bd-dxtc):
- Dry-run mode returns preview without actual deletion
- Invalid issue IDs return appropriate errors
- Partial success when some IDs valid, some invalid
- No IDs provided error case
- Invalid JSON args handling
- Response structure validation (deleted_count, total_count)
- Storage not available error
- Tombstone creation with SQLite storage
- All failures error handling
- Dry-run preserves data across multiple runs
