FastAPI application entrypoint.
Run with:
uvicorn src.ui.main:app --reload --port 8000
The frontend should call POST /chat with {"session_id": "...", "message": "..."}.
In production the built React bundle (src/ui/frontend/dist) is served from "/";
without a build, only the API routes are available.
