#### TX Fail Reset Threshold (tx.fail.reset)
Automatically resets the radio hardware after this many consecutive failed transmission attempts. This recovers from "zombie radio" states where the SX1262 stops responding to send commands.

Values: 0 (disabled) or 1–10 (default: 3). After the threshold is reached, the radio is reset and the failed packet is re-queued.
#### RX Stuck Reboot Threshold (rx.fail.reboot)
Automatically reboots the device after this many consecutive RX-stuck recovery failures. An RX-stuck event occurs when the radio is not in receive mode for 8 seconds despite automatic recovery attempts.
