fix: formatting and async test bug in hooks-config

- Fix Prettier formatting in ralph-tracker.ts and respawn-controller.ts
  (whitespace drift from Phase 2/4 refactoring)
- Add missing `await` to writeHooksConfig() calls in hooks-config.test.ts
  (async function was called without await, causing ENOENT race condition)
