One pending request for an absent track's immutable metadata, not a subscription.
The connection's events_to recipient owns provisioning. timeout_ms is the
decision window starting when MOQX receives the request, not when the caller
reads its mailbox. Registering the track resolves all pending requests for its
exact publication and name; it does not authorize any media subscription.
