[gap-decorations] Implement behavior of overlap-join for "dangling" endpoints

Widen the edge vs interior endpoint classification for CSS gap
decorations. Previously, "edge" meant the endpoint is at the container
boundary. The new definition: an endpoint is \<TODO> if it has no visible
crossing decoration, either because it's at the container boundary
(geometric edge) OR because it's an interior intersection where the
crossing decoration is hidden (dangling endpoint).

This is relevant for rule-visibility-items: between in grid containers,
where empty cells can suppress crossing decorations, creating interior
intersections that visually "dangle" without anything to join to.
