Refactor hook timeout settings to use centralized constants

- Introduced a new module `hook-constants.ts` to define timeout constants for various hooks.
- Updated `cleanup-hook.ts`, `context-hook.ts`, `save-hook.ts`, and `summary-hook.ts` to utilize the new `HOOK_TIMEOUTS.DEFAULT` for fetch timeouts instead of hardcoded values.
- Adjusted worker utility timeouts in `worker-utils.ts` to use constants from `hook-constants.ts`, improving maintainability and consistency across the codebase.
