Programmatic Control Setup - Copilotkit

<Steps> <Step> ### Run Claude through an AG-UI endpoint

Programmatic control starts from the same AG-UI run boundary as the chat UI.
Wrap Claude Agent SDK once, then trigger runs from a custom UI with
`useAgent` or the AG-UI client. Inside your component, add the user
message to the agent and dispatch the run.
