Introduced consistent preferences for external LoRa FEM RX and TX gain settings in NodePrefs. Updated companion MyMesh to apply these settings during initialization and transmission. Added unit tests to verify the round-trip serialization of these new preferences.
The room server never supported RX boosted gain, while the repeater
does. Three consequences on SX1262/SX1268 boards:
- boosted gain was never applied to the radio at boot, so a room server
ran in power-saving RX mode while an identical repeater ran boosted -
a real receive-sensitivity difference with nothing pointing at it
- _prefs.rx_boosted_gain was never initialised (the prefs are memset to
0 before defaults are set), so it defaulted to off
- 'set radio.rxgain on' replied "Error: unsupported" but CommonCLI had
already written the value to prefs and saved them, so a stale setting
survived reboot and was never applied
Mirror the repeater's implementation: initialise the pref default under
the same USE_SX1262/USE_SX1268 and SX126X_RX_BOOSTED_GAIN guards, apply
it during radio init, and override setRxBoostedGain() so the CLI reports
success and takes effect.
Built Heltec_v3_room_server (SX1262) and LilyGo_T3S3_sx1276_room_server
(guards compile out cleanly).
setTxTimeoutMs() and setTxBufferSize() are HWCDC-only APIs; calling
them on HardwareSerial (UART-bridge boards like T-Beam) fails to compile.

Switch ESP32-S3 KISS modem environments to HWCDC and move outbound KISS writes to a non-blocking queued frame path so loop() and TX completion keep progressing when the host reads slowly. Add native backpressure regression tests and correct the native_kiss_modem test filter so this suite runs directly with pio test.
The `recv_pkt_region` is set when processing a flood packet in `filterRecvFloodPacket`
but direct/non-flood packets would never pass through that function, so the pointer was
not cleared for them.
`sendFloodReply` would then later use it blindly, which meant that the response would
either inherit the region from the last flood packet, or refer to a non-initialised pointer
if no region floods had been received yet.
