feat(compact): add --dry-run to check file readiness without modifying

Browse Source 
- CLI: python main.py compact --dry-run [--db FILE]
- API: POST /api/compact {"dry_run": true}
- Checks .laccdb lock file + exclusive open to detect busy files
- Returns per-file [READY] / [BUSY] status with lock reason
