fix(git-hook): use HookService instead of non-existent GitServiceHooks

GitServiceHooks was renamed to HookService in the hook module refactor.
Updated main.rs to:
- Use HookService::new() with correct parameters (no http client)
- Call start_worker() which returns CancellationToken
- Wait on cancel.cancelled() instead of double-awaiting ctrl_c
- Clone token before moving into signal handler task
