Action-state 7 handler dispatched from CrewActionDispatch (33876, entry index 7). Called via JP (HL) from 36014. Calls 37876 to update the sprite position, then walks the two nearest-crew slots (33696 and 33697) — if either crew member is still alive, decrements one of the per-crew counters at offset -3 from its alive flag and, depending on the value, either jumps to 39400 or initiates a 29-step approach via 37176. Returns without further action if both nearest-crew entries are dead or absent (255).
