FATAL OOM → better-sqlite3 “database connection is not open” at session-manager.js:642 (macOS ARM, Node 23.3.0)

### Summary
Running `claude-flow` hits a V8 out-of-memory error. During shutdown, the app attempts to log a session event and `better-sqlite3` throws `TypeError: The database connection is not open` (likely after the DB handle is closed or never opened due to the crash).
