  • Demo Shell action executed and terminal output included right click menu action works
  • second plus left-click opened browser UI via cmux.newBrowser action
• Extracted frame thumbnails at 2, 6, 10, 16, 24, 34s for review: frame_2s.png, frame_6s.png, frame_10s.png, frame_16s.png, frame_24s.png, frame_34s.png (from 0.5s segments)
