Unify the trashed universe on the trash rows

02 rules the trashed side has exactly one definition: the set with trash rows — a card carrying its own deleted: under a tombstoned lane is in neither universe, so an anchor or selection can never survive on an item that renders nowhere. The membership rule now lives once, in Liveness.walk, and ItemReferenceSet.idUniverse, TrashModel.entries, paths, and emptyTrashTargets all derive from it — the old lane-OR-card logic that admitted subsumed cards to the trashed side is gone, and the two universes deliberately no longer partition the board. Put Back, Delete Immediately, and Empty Trash outcomes are unchanged: a tombstoned lane still moves and purges whole, its nested tombstones with it.
