Convert to PlatformIO/Arduino format

- Replace ESP-IDF structure with PlatformIO (platformio.ini) - Move source files to src/ and include/ - Move libraries to lib/ directory - Replace FreeRTOS with Arduino task/vTaskDelay - Use Arduino MIDI library instead of raw TinyUSB - Dual-core: MIDI on core 0, controller on core 1
