The old route is already down or switched away when a transition fires,
so waiting the default 5 s per slot for a DISCONNECTED event only delays
recovery (up to 25 s across five slots). A client whose event is late is
aborted by keepalive and retried by the normal backoff loop, the same as
the token-renewal path's softDisconnect() + reconnect().
