- Add WSL2 usbipd attach support and WSL1 COM-port fallback docs for the official nCS Zigbee NCP Host helper.
- Add bounded host validation runs with -RunSeconds.
- Record board1 transport validation: WSL1 opens COM27 as /dev/ttyS27 and simple_gw transmits NCP frames, but the current board1 firmware does not return the low-level ACK yet.
