Refactor hooks to ensure worker is running before processing

- Updated `save-hook.js`, `summary-hook.js`, `context-hook.ts`, `new-hook.ts`, and `save-hook.ts` to include a call to `ensureWorkerRunning()` at the beginning of their main functions. This ensures that the worker is active before any operations are performed.
- Cleaned up import statements in the affected files to include the new utility function from `worker-utils.js`.
- Minor adjustments to logging and error handling to improve robustness and clarity.
