ReconnectSupervisor swallowed a transport failure reported while Replaying, so a restarted event stream refused/ended a round trip after the replay began still let the replay go Healthy over a dead stream (and the next advise's re-report restarted at attempt 1 with no backoff). A failure reported during Replaying is now remembered and turns that attempt's success into a retry with backoff. ReplayAsync's synchronous dead-pump throw yields to a teardown's cancellation.
