The status stream emits a synthetic StatusDaemonUnavailable when the
gRPC client or stream cannot be established, fired once per outage and
cleared on the next real snapshot. The tray maps it to a "Not running"
status label, switches the icon to the error variant, hides
Connect/Disconnect (neither would work without the daemon), and
disables Settings, Networks and Create Debug Bundle so the user is not
routed to pages that would just fail to load.
