feedback1 integrate: 坚固维式重锤's 不死 lock is once per deployment (user decision 2026-10-03)

The carrier's own non-initial deploy (the redeploy after a knock-out, a 突袭 retreat +
redeploy) re-arms the lock and ends a window still running. The per-battle test is flipped
and a retreat + redeploy case added.
