### Wire CopilotKit middleware into your graph

Shared state flows between your UI and your agent through `agent.setState`
on the frontend and `state.get(...)` in your graph nodes. Attach
`CopilotKitMiddleware` to your `create_agent` call so CopilotKit-specific
state is picked up alongside your own.
