Cardputer Buddy app bundle

The buddy/ directory in the local build-with-claude clone is the MicroPython payload that m5-onboard installs onto /flash/. Work inside that clone.

Device layout

/flash/
├── main.py              launcher menu (replaces UIFlow's boot flow)
├── buddy_*.py           shared libs (BLE, UI, state, protocol, chars)
├── burst_frames.py      sprite frames
└── apps/
    ├── claude_buddy.py  BLE client → Claude Desktop's Hardware Buddy
    ├── hello_cardputer.py
    └── snake.py

main.py scans /flash/apps/ at boot and lists every .py as a menu entry. Drop a file into buddy/device/apps/, push it, and it appears on next boot.
