重构广播功能，从简单的回复转发模式改为更安全的会话模式： 1. 添加会话状态管理，60秒超时自动取消 2. 支持直接发送消息内容而非必须回复 3. 使用合并转发消息格式发送广播内容 4. 改进错误处理和状态报告 5. 添加类型提示和文档注释 同时修改相关API和模型： 1. 在GroupInfo中添加群备注和全员禁言字段 2. 改进get_forward_msg返回类型和兼容性处理 3. 清理不必要的Optional导入

管理员专用的广播插件

功能：

- 仅限管理员在私聊中调用。
|

- 通过回复一条消息并发送指令，将该消息转发给机器人所在的所有群聊。
|

- 此插件不写入 __plugin_meta__，保持隐藏。
