Returns the config seeded by the first connecting client.
Waits until at least one client has connected and supplied its config, so callers that need to
bootstrap observability / telemetry inside the shared worker do not have to independently
re-read Storage/Envs/Local/Defaults (which would duplicate what the main thread already did and
could drift from the client's view).
