The "default application suite" roadmap item, but deliberately NOT a
nomarchy.apps.* option surface: a bare package install has no config to
put behind a toggle, so a thin `mkIf x { systemPackages = [p]; }` only
reinvents what a package list already gives. Instead the suite is a
curated home.packages list in templates/downstream/home.nix (extending
the existing `# firefox` convention) — active staples (libreoffice,
vscode, gimp, inkscape, mpv, amberol) plus commented suggestions. The
opt-out is deleting a line; it also keeps the apps out of the live ISO
automatically (the ISO never scaffolds from the template).
The members that DO need system config become nomarchy.services.* opt-in
toggles instead (config behind the switch, like the existing services):
- steam → programs.steam (32-bit stack, controller udev, RP ports)
- libvirt → libvirtd + virt-manager, login user added to libvirtd group
- obs → obs-studio + a v4l2loopback virtual camera (exclusive_caps=1)
selectable as a webcam in Zoom/Teams
README option table, ROADMAP (services item now "Eight shipped"; suite
item marked done with the no-surface rationale) and the downstream
system.nix examples updated to match.
