[useAssistant] Add status for when a "tool_calls" run step is in progress.

[Pascaltib]

When using useAssistant there are currently only two statuses available 'in_progress' | 'awaiting_message'.

However, it would be nice to display a specific method when running a tool call which would normally take a bit longer. This is something the OpenAI assistant playground does where they show UI saying something along the words of "running retrieval". This UI is very helpful to show the user what work you are doing behind the scenes to answer their prompt.

The way to detect this would be to detect when a thread.run.step.created event is triggered and the data has type: 'tool_calls'.

It would also be amazing to have the specific tool being used in the frontend as a status. This is only available in the thread.run.step.delta and I am not sure if this is after the tool is done being used.
Example using "file_search" tool:

{
  "data": {
    "id": "...",
    "object": "thread.run.step.delta",
    "delta": {
      "step_details": {
        "type": "tool_calls",
        "tool_calls": [
          {
            "index": 0,
            "id": "...",
            "type": "file_search",
            "file_search": {}
          }
        ]
      }
    }
  }
}

This is exactly what I have been trying to figure out.

Currently, it seems that there is no possible way to show the users what is really happening behind the scenes instead of just having a loading spinnner.

Has anyone figured out a way to do this?

I have tried by doing the following, but its not working as expected. The status update messages disappear.

const statusContent = 'Thinking...'
const statusUpdate: StatusUpdate = {
    type: 'status-update',
    content: {
      id: generateUUID(),
      role: 'assistant',
      content: statusContent,
      createdAt: new Date().toISOString(),
      chatId: chatId
    }
  }
dataStream.writeData(statusUpdate);
