Desired behavior locked:
- dead PC not removed from turnOrderIds
- dead PC turn still comes up (nextTurn visits them)
- dead PC on their turn can deathSave
- dead PC not auto-set isActive=false by applyHpChange
All 4 RED on current code. Root cause: nextTurn filters isActive,
applyHpChange sets isActive=false on death, computeTurnOrderAfterRemoval
drops dead from turnOrderIds.
TODO BUG-3/M4 updated with test refs.
