register_ucp_profile

Register a public hosted UCP agent profile and receive agent_id/profile_url. Default path: send agent_name plus public_key_jwk and the gateway builds the canonical UCP profile with default Shopping capabilities. Re-registering the same public_key_jwk in the same namespace is idempotent and returns the existing agent_id. Do not build a capability map for normal registration. Create local ./.ucpgateway/ files; keep private_key.jwk local and save returned agent_id/profile_url/profile_json to ./.ucpgateway/agent.json.
