virt-manager on niri/Noctalia failed with 'authentication unavailable:
no polkit agent available to authenticate action org.libvirt.unix.manage'
- bare compositors ship no polkit agent, unlike GNOME/KDE.
Two fixes:
- install_session_prereqs installs polkit-gnome and wires its agent
.desktop into /etc/xdg/autostart (paths overridable for testing).
- niri module optionally installs the qemu/libvirt stack, enables
libvirtd, and adds the user to the libvirt group: members manage
qemu:///system with no polkit prompt at all (the real fix; applies
after re-login).
