React: persistence: true is not working in useChat

@tanstack/ai-react version

Framework/Library version

React v18

Describe the bug and the steps to reproduce it

import { fetchServerSentEvents, useChat } from '@tanstack/ai-react';

function Chat() {
  const { messages, sendMessage, isLoading, error } = useChat({
    threadId: '1',
    connection: fetchServerSentEvents('http://localhost:8080/api/v1/chats'),
    persistence: true,
  });
}

I want my chat to be persistent and keep chat messages on the server side.
So, I am setting persistence: true according the docs.

However TypeScript says:

Type 'boolean' is not assignable to type 'ChatClientPersistence<any>'

And there is no GET request when my component mounts to fetch initial messages.

Dependencies:

"@tanstack/ai": "^0.42.0",
"@tanstack/ai-react": "^0.18.1",
"react": "^18.1.0",
"react-dom": "^18.1.0"

What I am doing wrong?
