Commit Message

Add per-session schema cache and switch EngineFactory to Arc (#78)

- Introduce an LRU schema cache to Session for faster schema_for_query.
- Invalidate schema cache on DDL or catalog-changing statements.
- Replace Arc<Mutex<EngineFactory>> with Arc<EngineFactory> throughout.
- Enforce max_sessions via a semaphore in SessionRegistry.
- SessionRegistry now holds session permits to prevent session leaks.
- EngineFactory connection creation moved to spawn_blocking to avoid blocking async tasks.
