Config was symlinked from ~/.dots/quickshell (separate dotfiles repo); now
tracked here and applied via home-manager xdg.configFile.

Replaces CachyOS on the OS SSD (Kingston SA400, disko-managed). Dev-data
disks (sdc ext4 /mnt/hdd_01, LVM vg_ssd /mnt/ssd_01) stay out of disko and
are mounted as plain filesystems so they're never wiped. Desktop split into
services/desktop/desktop-hyprland.nix (session: compositor, greeter, audio,
portals) and desktop-apps.nix (things darman actually launches, including
claude-code — allowlisted alongside the other unfree desktop apps).
