connector/discover/digital-twin-registry/auth

Get authorization to a counterparty's Digital Twin Registry.

Finds the registry asset in the counterparty's catalog by its standard dct:type, negotiates it, and publishes the resulting dataplane_url and edr_token — exactly what the digital-twin-registry/consumer/dataplane/* steps read.
