Initial Tdarr-tray: KDE systray applet for the Tdarr workstation node

PyQt6 QSystemTrayIcon: green=running, red=stopped, yellow=transition.
Pause/resume the node via the API (frees/reclaims the GPU, no sudo) so you
can free the 4060 Ti before gaming. Playbook standard: README (per-OS
prereqs + build/run/test), doc/plan.md, .gitignore (build/ first), VS Code
build task -> ./build, install.sh + one-line curl (clone or release),
Gitea Actions rolling-latest release.
