调用OpenAI Assistants API连接线程报错：'Thread'对象不可下标访问

错误出在thread["assistant"]这行代码——调用client.beta.threads.retrieve()返回的是Thread实例对象，不是字典，不能用下标[]访问属性，必须用点.语法访问对象属性。另外，Thread对象中存储助理ID的属性是assistant_id，不是assistant。

修改后的代码如下：

def connect_helmsman_gpt():
    config = load_config()
    api_key = config.get("api_key")
    thread_id = config.get("thread_id")
    if thread_id is None:
        print("No thread ID found in config")
        return None, None, None
    
    try:
        client = OpenAI(api_key=api_key)
        thread = client.beta.threads.retrieve(thread_id)
        # 修正属性访问方式和属性名
        assistant = client.beta.assistants.retrieve(thread.assistant_id)
        return assistant, client, thread
    except Exception as e:
        print(f"Failed to connect to the GPT thread: {e}")
        return None, None, None
