When the OPAL server is configured with a broadcast URI containing an unresolvable hostname, the gaierror exception was silently swallowed and only logged at DEBUG level by the underlying fastapi_websocket_pubsub library. This made it extremely difficult for operators to diagnose misconfigured broadcast URIs. Changes: - Add _validate_broadcast_uri() in PubSub that performs an early DNS resolution check at startup and logs at ERROR level if it fails - Replace the anonymous lambda broadcaster disconnect callback with _on_broadcaster_disconnected() that inspects the task exception and logs it at ERROR level (catches the gaierror at runtime too) Both changes are advisory only -- they do not prevent startup or change existing control flow, preserving backward compatibility.

Description
Fixes the silent swallowing of DNS resolution errors for the broadcast URI. The
gaierrorwhen resolving the broadcast hostname was previously logged at DEBUG level, making it extremely difficult for operators to diagnose misconfigured broadcast URIs.Closes #716
