Detailed Description

Nuke DB Context.

Logic:

1. Init: Load disk DB into Memory DB. Enables WAL mode on disk.
2. Runtime:
   • SELECTs happen in Memory.
   • INSERT/UPDATE/DELETE trigger immediate background sync to Disk on COMMIT.
3. Periodic: Background thread also performs periodic sync as a fail-safe.
4. Exit: Catch signals (SIGINT, SIGTERM) and force final Sync.
