feat: Add visual progress indicators to sync operations

- Implement ProgressReporter interface with InteractiveProgress and NoOpProgress
- Add real-time progress bars using go-pretty/progress library
- Track 6 sync phases: connection test, queue push, pull, parse, apply, and server push
- Add --quiet flag to suppress progress output
- Auto-detect TTY to disable progress when piped/redirected
- Show task-level progress during apply phase with descriptions
- Display percentage complete and elapsed time for each phase
