Prevent stale events from shards that ended naturally (not via
stopMonitor). handleMessage now gates on gameFinished in addition to
manuallyStopped. handleEntityUpdate properly cleans up on gameFinished
by emitting room.disconnected, removing from activeShards, and calling
disconnect. handleError also removes from activeShards. Probe message
handler and status broadcast bail out when the shard is stopped or the
game has finished.
