fix: Hide console window on Windows when spawning child processes (#166)

* fix: Hide console window on Windows when spawning child processes

Add windowsHide: true to spawnSync and execSync calls to prevent
empty console windows from appearing on Windows when hooks execute.

Fixes two spawn points:
- worker-utils.ts: PM2 spawn when starting worker service
- user-message-hook.ts: Node spawn for context display

Reference: https://nodejs.org/api/child_process.html (windowsHide option)

* fix: Add windowsHide to remaining execSync calls for complete Windows console window hiding

This completes the Windows console window fix by adding `windowsHide: true` to all remaining `execSync` calls:

- src/services/worker-service.ts:220 - pgrep command for orphaned process detection
- src/services/worker-service.ts:226 - pkill command for process cleanup
- src/services/worker/SDKAgent.ts:414 - where/which claude command for finding executable

These operations are less frequent than the user-prompt hook, but should still avoid spawning console windows on Windows for a complete fix.
