Implements MicroPython emulation for Raspberry Pi Pico boards running
entirely in the browser using rp2040js. Users can toggle between
Arduino C++ and MicroPython modes via a language selector dropdown.
Key changes:
- Add LanguageMode type and BOARD_SUPPORTS_MICROPYTHON to board types
- Create MicroPythonLoader.ts: UF2 firmware parser, LittleFS filesystem
builder (via littlefs-wasm), IndexedDB firmware caching
- Extend RP2040Simulator with loadMicroPython() method using USBCDC for
serial REPL instead of UART
- Add setBoardLanguageMode and loadMicroPythonProgram store actions
- Update EditorToolbar with language toggle and MicroPython compile flow
- Enhance SerialMonitor with REPL label, Ctrl+C/D support
- Bundle MicroPython v1.20.0 UF2 firmware as fallback in public/firmware/
- Update useEditorStore to create main.py default for MicroPython mode
