GNOME-only autostart entry installed to /etc/xdg/autostart/. Uses
X-GNOME-Autostart-Phase=Initialization so it runs before user
autostarts but after GDM hands the session off. NoDisplay=true keeps
it out of the apps menu — autostart-only.
Plan deviation: project uses debian/rules for installation (no
debian/authforge-gui.install file exists), so the install line goes
there instead.
