discord.py非异步上下文无法访问loop属性的问题修复求助

运行Discord机器人代码时，机器人能正常启动，但执行/profiles命令时触发以下错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: loop attribute cannot be accessed in non-async contexts. Consider using either an asynchronous main function and passing it to asyncio.run or using asynchronous initialisation hooks such as Client.setup_hook

其他命令运行正常，多次修改（如将get_uuid设为异步函数）仍未解决。

1. 异步方法调用遗漏await：client.wait_for是异步方法，调用时未加await，导致在非异步上下文尝试访问事件循环属性。
2. 异步函数调用未加await：get_uuid是异步函数，调用时未加await，触发上下文冲突。
3. 冗余客户端实例：代码同时创建discord.Client和commands.Bot实例，造成上下文混乱。
4. 同步请求阻塞事件循环：使用同步requests.get在异步环境中运行，虽不是直接触发当前错误，但会影响机器人性能。

关键修改点 #

• 移除冗余的discord.Client实例，统一使用commands.Bot
• 所有异步方法/函数调用必须添加await关键字
• 将同步HTTP请求替换为异步aiohttp请求，适配Discord.py异步环境

• 所有原同步HTTP请求改为异步，避免阻塞机器人事件循环
• wait_for增加了频道校验，确保只接收当前频道的用户输入，避免跨频道干扰
• 发送JSON数据时使用json.dumps格式化，提升消息可读性
