please support langchain AgentExecutor stream function

[qingtian1771]

Feature Description

At present, it can only support langchain LLM model stream, for example following code:

const stream = await model.stream(
    messages.map(message =>
      message.role == 'user'
        ? new HumanMessage(message.content)
        : new AIMessage(message.content),
    ),
  );

  return new StreamingTextResponse(LangChainAdapter.toAIStream(stream));

but If I want to use agent and I want to call AgentExecutor to stream the output, it will not work

const agentExecutor = new AgentExecutor({
  agent,
  tools,
});
const stream = await agentExecutor.stream({
  input: "hi!",
});

please support this function, thanks!
