Version: 0.9.41.dev.260424

后端：
1. 随口记从 Execute 工具链路迁移到独立 QuickTask 轻量节点——单轮流式提取意图直接调 service，绕过 ReAct 循环
- 新增 QuickTask graph 节点 + Chat→QuickTask→END 分支
- Chat 路由提示词新增 quick_task 路由判别规则，execute 路由收窄为日程类
- Execute 提示词（有 plan / ReAct 两套）移除 quick_note_create / query_tasks 指令
- ToolRegistry 注销 quick_note_create / query_tasks，移除相关依赖与注册
- 依赖注入从 ToolRegistry 改为 Service 层直接注入 QuickTaskDeps

2. urgency_threshold_at 代码兜底 + API 返回补全
- priorityGroup=2 且有 deadline 但 LLM 未填时，自动设为 deadline-24h
- 任务查询接口返回结构补充 UrgencyThresholdAt 字段与转换映射

3. 记忆召回条数 5→10
