Repair alias-only launchers for flat apps too; never fail on a VR alias

Review follow-up. inspect() now returns 'repairable' and the filters it can
patch: the real activity's VR MAIN filter, or, when LAUNCHER/VR sits only on an
<activity-alias>, any real MAIN filter with a category to copy. install() and
patch() repair on 'repairable' instead of 'vr_activity', so a flat Godot 4
export is fixed and a VR category only on the alias no longer aborts install.
Tests cover both shapes, an already-launchable activity with an alias, and an
end-to-end patch.
