- Add TCP connectivity pre-test before guacd handshake — gives a clear
error message if the RDP host is unreachable from the Docker network
- Add disable-gfx:true (disables GFX Pipeline Extension, known FreeRDP
2.x crash source on Windows 10/11) and cert-tofu:true
- Log tcpBuf flush content and all guacd data at debug level so we can
see exactly what guacd sends after the ready instruction
