test: a lab that runs a real desktop where no VM can exist

The development host is a VM without /dev/kvm, so a candidate desktop cannot be given a virtual machine here. It gets a systemd container instead, with the session nested inside a headless sway so that grim can photograph it and sway's IPC can aim a real pointer at it. Plasma 6.3.6 comes up in it, software-rendered, at 1920x1080. Co-Authored-By: Claude Opus 5 <[email protected]>
