Add useStream support for vueJS

Hello,

Do you think it’s possible to add the support of useStream for Vue.js (currently only react is supported)?

libs/sdk/src/react/stream.tsx

main

import { useState } from "react";
import { useStreamLGP } from "./stream.lgp.js";
import { useStreamCustom } from "./stream.custom.js";
import type { UseStreamOptions, InferAgentState } from "../ui/types.js";
import type { BagTemplate } from "../types.template.js";
import type {
  UseStream,
  UseStreamCustom,
  UseStreamCustomOptions,
} from "./types.js";

function isCustomOptions<
  StateType extends Record<string, unknown> = Record<string, unknown>,
  Bag extends BagTemplate = BagTemplate
>(
  options:
    | UseStreamOptions<StateType, Bag>
    | UseStreamCustomOptions<StateType, Bag>
): options is UseStreamCustomOptions<StateType, Bag> {
  return "transport" in options;

Vue.Js is also a big frontend framework.

hi @Jourdelune

I just pushed a PR for this feat(sdk): add Vue 3 useStream composable by pawel-twardziak · Pull Request #1933 · langchain-ai/langgraphjs · GitHub
Please do a CR and if you know someone else who could do the code review that would be great
