AG-UI integration

When to use

• The user is building a web UI (React / Next.js / anything HTTP+SSE) that should talk to an AG2 agent.
• They want streaming text, reasoning, tool-call rendering, shared state sync, or sub-task step tracking surfaced to the frontend with a standard protocol — not a custom REST/WebSocket contract.
• They're using or considering CopilotKit (the recommended React client).

For a custom narrow-purpose API where you own the contract end-to-end, skip AG-UI and write a plain endpoint instead.
