The official guacamole/guacd image ships FreeRDP 2.x, which crashes
silently when connecting to Windows 11 22H2+ hosts due to NLA/CredSSP
cipher-suite changes. FreeRDP 3.x resolves this.
- docker/guacd.Dockerfile: builds guacamole-server 1.6.0 from source on
Ubuntu 24.04 against freerdp3-dev (FreeRDP 3.5.1+); uses
CPPFLAGS=-Wno-error=deprecated-declarations to suppress upstream
deprecation warnings in freerdp3 headers
- docker-compose.yml: switch guacd service from official image to local build
