The supersession rule fires on TaskLeased, and a failed task is never
leased again. Run 12's rig task reached retry_limit still holding a
transaction whose commit the coordinator refuses permanently, so it kept
asking every five seconds with nothing that could ever change.
Terminal means terminal: TaskFailed now drops the transaction and
quarantines the session even when the anchor was pushed. Blocked keeps
the old rule, because a reopen still produces a successor that can pick
the anchor up.
