v6.3.0-beta.9

7.0.0-beta.8 (2026-06-07)

⚠ BREAKING CHANGES

• RegistryClient.create_adagents now returns a CreateAdagentsResponse Pydantic model instead of dict[str, Any]. Callers using subscript access (result["success"], result["data"]) must switch to attribute access (result.success, result.data). The model matches the /api/adagents/create wire contract (adcp#5385).
