setup.status returned True whenever any provider auth state was discoverable, including indirect fallbacks like a gh-CLI Copilot token. That made desktop think the user was set up while the agent's actual resolve_runtime_provider call still raised AuthError, leaving the user with a useless toast and no onboarding.
Add a setup.runtime_check gateway method that runs the same resolver the agent uses on session creation, and switch the desktop onboarding overlay and prompt precheck to use it.
