GNOME mínimo: instala escritorio curado en setup.sh, no el grupo gnome

El perfil GNOME de archinstall instala el grupo 'gnome' completo (Maps,
Weather, Music, Tour, Web/Epiphany, Contacts, Rygel...). Se quita el
profile_config: archinstall instala solo la base, y gnome/setup.sh pone una
lista curada (gnome-shell, gdm, control-center, nautilus, console, text-editor,
calculator, loupe, tweaks) + drivers gráficos open-source (mesa/vulkan) y
habilita gdm. KDE pendiente del mismo tratamiento.
