Transparent LoRa-over-USB dongle firmware supporting Heltec V3 (ESP32-S3) and RAK 4631 (nRF52840) boards. Actor-model architecture with typed channels between USB, radio, and display tasks. - Protocol: Command/Response enums with COBS+postcard framing design - Board abstraction: auto-discovered via build.rs Jinja2 codegen - Radio task: SX1262 state machine (Idle → Receiving ↔ Transmitting) - Display task: optional SSD1306 dashboard via StatusWatch - RAK 4631: fully wired SPI/USB/I2C peripherals, clippy-clean - Heltec V3: structure in place, awaits espup Xtensa toolchain
