feat: AI 工具架构重构与微信增强 (0.2.17 → 0.2.22)

0.2.17 收束模型初始工具列表：
- 仅暴露 query_capabilities/query_capability_detail/call_capability 三个入口
- API 能力统一通过 iAs HTTP API 封装，删除重复 YAML 工具

0.2.18 系统提示词拆分：
- 固定系统提示词硬编码，动态附加部分 AI 可维护
- 新增 update_additional_system_prompt 能力和持久化

0.2.19 上下文增强与打断语义：
- /new 拥有最高打断语义，取消运行中任务并清除当前 turn
- raw_message JSONB 原文入库，群聊按 group_id 隔离作用域
- 工具调用说明替代动态附加系统提示词

0.2.20 微信输入中状态：
- 改用官方 getconfig + sendtyping 流程，显式管理 typing 状态

0.2.21 API 文档功能分组：
- /v1/api-docs 返回 groups，帮助 AI 按功能面发现接口

0.2.22 AI API 能力去重：
- 移除与 HTTP endpoint 重复的专用能力，统一用 query_api_docs + call_http_api
- 删除不再编译的 web/memory 工具文件
