OneBot 11 适配器：反向 WS 接入 QQ（NapCat/Lagrange）

- app/onebot.py: /onebot/v11/ws 反向 WS；私聊全回、群聊仅回应 @她 并自动 @ 回去
- CQ 码字符串与消息段数组双格式解析；会话 id ob-<self_id>-p/g-<目标> 与 TUI 隔离
- action echo 配对调用（send_private_msg / send_group_msg），retcode==0 才落历史
- remember_later 的推送（事件确认/关怀/连续天数/身世）自动转成 QQ 消息
- 主动消息路由：push_proactive 优先 TUI、ob- 会话走 QQ，均不在线保持 pending
- 主干重构：chat_turn() 供 TUI 与 OneBot 共用；助手消息由传输层确认送达后落库
- 可选 OB_ACCESS_TOKEN 令牌校验；8 个新测试（回复/CQ剥离/群@/通知转换/主动推送/令牌）
