Once your ADK agent is deployed, this gets it registered with Gemini Enterprise so users can actually discover and invoke it. Handles both standard ADK registration (via reasoning engine ID) and A2A protocol agents (via agent card URL). The smart bit is auto-detection: if you have a deployment_metadata.json from agents-cli deploy, it reads your runtime ID, figures out whether you're using A2A, and constructs the card URL automatically. You still need to create the Gemini Enterprise app in Cloud Console first and pass its ID, but after that it's mostly flags or interactive prompts. Watch out for the SDK version issue with google-cloud-aiplatform 1.128.0 and earlier causing session errors post-registration.
