- 彻底移除「每 N 次请求强制思考」的间隔调度机制（思考/非思考交替导致缓存命中率极低） - 运行模式收敛为 fast/thinking：原 deep 改名 thinking，历史数据读取时映射 - 新增推理强度五档滑块（low/medium/high/xhigh/max + 默认不传参），置于模型/模式弹窗 - 模型配置新增 reasoning_effort 开关；档位会话级持久化到对话 meta，随对话保存/恢复 - 个人空间新增「默认推理强度」；新用户默认运行模式改为 thinking - 滑块交互：JS 插值驱动（点击/拖动/吸附全程平滑），首帧档位语义定位无闪烁 - 保存链路：前端防抖 600ms + conversation_id 兜底，修复 /new 发消息丢档位、切对话恢复错误
