- 同步阻塞操作（附件处理、历史加载、scheduler/memory_search 的 SQLite 调用） 移入 spawn_blocking，避免占用 async worker - LLM Provider reqwest::Client 按超时配置缓存复用，减少 TLS/连接开销 - agent loop：图片过滤加廉价预判避免全量深拷贝；请求克隆改借用；工具定义 Arc 化 - 定向 COUNT/LIMIT 1 查询替代全量加载计数（wait_coordinator、task session 重建） - 前端：面板/侧栏/聊天组件 memo 化；merged_tool 对象按值复用缓存； 流式 delta rAF 节流批量 flush；useMemo 缓存分组排序结果
