- Track active (white ring) and current (green dot) snapshots on timeline
- Auto-capture "Current" state before swapping so user can navigate back
- Add "Snapshot" button to timeline bar for quick manual captures
- Register Ctrl+S / Cmd+S shortcut for manual snapshots
- Clear active/current markers on new captures and workflow switches
- Return record.id from captureSnapshot (backward-compatible truthy value)
