Brandon ThomasandClaude Opus 5.5 e7b3724b5f M1.4: crash-safe catalog persistence (op log + snapshot)

- catalog: Store trait (FsStore: temp+fsync+rename+dir fsync; MemStore),
  Journal: CRC-checked JSON-lines op log with sequence numbers + atomic
  snapshots; torn final record dropped and truncated, stale records after a
  snapshot skipped, mid-log damage preserved as catalog.log.damaged-N.
- PushHistory op so each edit logs one history step (not the full history).
- engine: Session::open_library/persist/close_library; every top-level
  command is fsynced before returning; presets.json + view.json;
  library.info / library.compact commands.
- app: default library ~/Pictures/LightCraft Library (LIGHTCRAFT_LIBRARY or
  --library DIR override), --memory for throwaway sessions, snapshot on quit.
- tests: proptest replay(log)==state with random snapshots/reopens, every
  truncation of the last record, stale log, mid-log damage, FsStore, engine
  restart without close.
