Enhance HooksDatabase and WorkerService functionality

- Updated save-hook.js and summary-hook.js to include new database columns for tracking worker ports and prompt numbers.
- Implemented migration logic to remove UNIQUE constraints from session_summaries table and added necessary indices.
- Modified HooksDatabase methods to return boolean values indicating success or failure of updates.
- Changed logging from error to info level in WorkerService for better clarity on session management and initialization.
