portersky c9ea1a6919 feat: port MT76 radio init and CLI tool
Complete the radio bring-up sequence: init_registers now writes the
upstream register values (PBF out of reset, beacon TX off), crystal
calibration, MAC/BSSID programming, channel evaluation, and beacon
programming through an MCU burst into PBF shared memory. The beacon
txwi is the full 20-byte struct and the RF patch is applied on the
cold firmware path.

Download firmware per product (xone_dongle_02e6.bin / 02fe.bin) and
add the xone_cli debug tool (info, firmware, radio-init/deinit, burst,
reg-read/write, led, recover). Recover uses USBDeviceReEnumerate for a
host-side port reset.
