Ryan Malloy 0e7b8c2ef5 Fix docs to match UART0 firmware implementation ...

The firmware uses UART0 (via USB bridge) with ESP-IDF console disabled,
not UART1 on GPIO4/GPIO5 as originally documented. Updated both docs to
reflect the actual hardware-verified configuration:

- protocol-spec.md: UART peripheral description
- hardware-setup.md: wiring section, monitor section, sdkconfig table,
  troubleshooting steps
