feat!: intents 只按大类订阅、群消息全量模式与事件流优化

破坏性变更：intents.toml 订阅粒度收敛到 Intents 大类（分组）——
配置从「[分组] 表内逐事件开关」改为「分组名 = true/false」。网关只接受
分组位掩码，组内事件本就无法单独订阅，此前的逐事件开关仅是「组内任一
为 true 即订阅整组」的装饰。旧格式不再兼容，与拼错的分组名、非布尔值
一样在启动时直接抛 ValueError，而非静默少订阅。

新增：
- GROUP_MESSAGE_CREATE 事件接收（群消息全量模式，与 GROUP_AT_MESSAGE_CREATE
  共用 GroupAtMessage）；GroupAtMessage 补齐 message_type/message_scene/
  attachments/mentions/ark_data/msg_elements 字段

优化：
- 形参注入缓存化：合并缓存 handler 签名与类型标注解析（此前每条事件都重跑
  inspect.signature/get_type_hints），services 命中改为每条事件实时判定，
  保证「先注册 handler、后登记组件」的既有装配顺序不受影响
- EventQueue.put_event/put_reply 去掉多余的 return await
- model.NoneType 联合成员顺序调整（None 置于末尾）

文档同步 GUIDE/API/README/CHANGELOG 与示例；测试 76 全绿，ruff/pyright 干净。
