Refactor hooks and worker service for improved session management and logging

- Updated new-hook.js, save-hook.js, and summary-hook.js to enhance logging and session handling.
- Simplified session auto-creation logic in worker-service.ts to prioritize observation data preservation.
- Added a blocking wait in ensureWorkerRunning function to prevent race conditions during worker startup.
- Improved error handling and logging consistency across hooks.
