+- `killturn` acts as an inactivity counter; it is reset to `game_env.killturn`
+  when a non-rest player action completes, and decremented for NPCs, autorun,
+  rest commands, or block states.
+- `block >= 2` forces `killturn` decrement and logs a block message.
+- When `killturn <= 0`, the general is converted to NPC (owner removed) or
+  deleted depending on NPC type and `deadyear`.
+- `autorun_limit` is stored in general `aux` and used to decide AI takeover.
