🤖 Add detailed timing logs for useResumeManager and UI ready

Add logs to pinpoint when auto-resume blocks the UI:

1. useResumeManager effect setup
2. Initial workspace check (runs on mount)
3. attemptResume start/finish for each workspace
4. resumeStream IPC call duration
5. App fully mounted and interactive marker

This will show if the first-launch freeze is caused by:
- useResumeManager checking interrupted streams
- resumeStream IPC taking 10s on first run
- Or something else entirely
