Subject: [PATCH] test(desktop): the no-heartbeat check expects the capability
 advertisement

Same stale invariant the ui-tui test had: since the shared channel sends one
client.capabilities frame on every gateway.ready, "no frames" is no longer
what this case guards. What it guards is that an older backend without
heartbeat gets no gateway.ping and stays open, so assert the wire holds
exactly the advertisement.
