Description

The AG-UI integration README's server example does not run as written:

• It imports get_ag_ui_workflow_router from llama_index.protocols.ag_ui.server, but the package has no server module, so the example fails with ModuleNotFoundError: No module named 'llama_index.protocols.ag_ui.server'. The factory lives in llama_index.protocols.ag_ui.router (which is also what the package tests import).
• router.py imports fastapi at module level, but FastAPI is only installed through the package's fastapi extra ([project.optional-dependencies]). With the README's pip install llama-index-protocols-ag-ui, importing the router fails with No module named 'fastapi'.

Changes (README only):

• Import from llama_index.protocols.ag_ui.router.
• Install with pip install "llama-index-protocols-ag-ui[fastapi]" and note that the example also needs uvicorn.
• List the two router parameters the README was missing (timeout, workflow_factory), matching get_ag_ui_workflow_router's signature.

Checked in a clean venv with llama-index-protocols-ag-ui==0.6.0: the .server import raises ModuleNotFoundError, the router import fails without FastAPI, and from llama_index.protocols.ag_ui.router import get_ag_ui_workflow_router works once the fastapi extra is installed.

AI disclosure: I used an AI assistant to help find this and draft the change. I reviewed the diff and verified the imports locally.
