Raw LoRa packets to and from a host over the USB/console serial port, plus
upstream's SetHardware extensions (identity, crypto, radio config, stats).
- app/KissModem.cpp/h: upstream text, ZephCore changes fenced: an LBT
refusal returns to CSMA until the wait-clear bound; a TX times out only
once the radio has concluded (as Dispatcher::loop); SetRadio outside the
ZC_RADIO_* ranges is refused; msUntilNextTx() for the event loop.
- src/main_kiss_modem.cpp: event-driven composition root; runs the radio
maintenance the Dispatcher would. Identity in /lfs/repeater/_main.id.
- adapters/transport/ZephyrUartStream: Arduino Stream over IRQ RX/TX rings.
- boards/common/kiss_modem.conf: role, BT off, console driver off.
- LoRaRadio::getCurrentRSSI(), Print::availableForWrite().
- UI mesh-action stubs for every non-companion role.
Tested on 2x XIAO ESP32-C3 + Wio-SX1262 at 869.423 MHz SF7/62.5/CR5.
Built for xiao_esp32c3, rak4631, lora_e5_mini; host tests pass.
