When the optional metrics feature is enabled, Wireframe updates the
wireframe_connections_active gauge, frame counters tagged by direction, error
counters tagged by kind, and a counter for panicking connection tasks. All
helpers become no-ops when the feature is disabled so instrumentation can stay
in place.[^33] handle_connection, the connection actor, and the panic wrapper
call these helpers to maintain consistent telemetry.[^6][^7][^31][^20]
