## Summary by cubic
Fixed deployment issues by updating concurrency settings, improving Gmail API calls, and adjusting wrangler configuration for new classes.

- **Bug Fixes**
  - Set thread processing concurrency to 1 to prevent overload.
  - Improved Gmail API label and thread fetching logic.
  - Added delay in thread syncing to reduce rate limit errors.

- **Dependencies**
  - Updated wrangler.jsonc to register new SQLite classes for deployment.
