Rev 14: elimination sweeps the board by either door

Two ways out of the game, one cleanup. A wizard killed by damage took
their monsters, sustained spells, and armed ambushes with them; a
wizard eliminated by treasure loss left everything standing — a fire
imp scorching for a dead master, a Medusa still gazing at a corpse.
Both paths now share one sweep, gated at rev 14 so stored games keep
their orphans acting as recorded.

Also: Lifesaver lasts until used, carried as a near-billion-turn
sentinel — which the scoresheet printed. Durations that mean forever
no longer show a number.
