Version: 0.9.39.dev.260423

后端：
1. 记忆系统移除 todo_hint 类型——随口记已由 Task 系统承接，todo_hint 语义重叠且无完成追踪
- 全链路清理：常量、校验、默认重要度、30 天 TTL、读取预算、LLM 抽取提示词枚举
- 总预算从四类收缩为三类（preference / constraint / fact）

2. 记忆抽取触发点从 chat-persist 移至 graph-completion——避免随口记消息被误提取为 constraint/preference
- chat-persist consumer 不再自动入队 memory.extract.requested，仅负责聊天历史落库
- graph 完成后新增条件发布：检测 UsedQuickNote 标记，调用过 quick_note_create 则跳过记忆抽取
- ResetForNextRun 重置 UsedQuickNote，防止跨轮残留导致后续正常消息记忆抽取被误跳过

3. 任务类查询接口返回 items 补充数据库主键 ID（前端拖拽编排依赖此字段）

前端：
4. 排程视图新增手动编排模式——侧边栏任务块拖拽入周课表 + 悬浮删除热区 + 建议块虚线标识
- TaskClassSidebar 拖拽发起 + 预览态嵌入时间格式化（含周次/星期）
- WeekPlanningBoard 外部拖入 / 内部移动 / 悬浮删除区交互
- ScheduleView 手动编排状态机（进入/退出/取消/覆盖确认）+ apply 时同步处理新增与删除
