🔀 变更说明 | Description of Change

重构 chat store 中 message slice （当前太大了，总共 30 个 actions），考虑未来 message 还会支持多选、批量删除等操作。AI 对话部分会进一步增强能力，因此提前拆成两个 slice：

• message slice: 承载所有 message 的增删改查和基础交互，actions 总共 21 个；
  • 增：（1 外部 + 2 内部）
  • 删：（4 外部 + 1 内部）
  • 改：（3 外部 + 3 内部）
  • 查：（2 外部 + 3 内部）
  • 副作用： 2 外部
  • 由于 message 作为基础实体，增删改查相关的实现已经基本完备，因此基础实现不会膨胀；
  • 未来的进一步优化思路是将 message slice 作为 aiChat slice 的基础方法来使用，因此可以考虑优化接口和收敛实现；
• aiChat slice: 承载所有 ai chat competition 的实现 （9 个），后续 rag 也提取到该 slice 中
