feat(03-02): implement ProgressMonitor class

- Add ProgressInfo dataclass for progress data
- Add ProgressMonitor class with:
  - PROGRESS_PATTERNS for extraction (percentage, fraction, phase, completion)
  - extract_progress() to find progress indicators in output
  - should_send_update() with 60 second throttling
  - create_progress_card() for Feishu card formatting
- Fix fraction pattern to allow content after fraction (e.g., [3/5 tasks])
- Fix should_send_update() to return False on first call
- Fix test assertions to use kwargs instead of positional args

All 7 tests pass for progress monitoring.
