feat: complete frozen MVP — period-aware stats, layout-driven UI, quick checkin

- Fix first daily record 422 (expectedVersion now accepts 0)
- Add period_window + summarize; /api/summary and /api/tasks/{id}/summary
  aggregate each metric inside its own day/week/month/lifetime window,
  reading raw facts only (never the rebuildable month archives)
- Drive frontend rendering from per-page layout JSON with a component
  registry; scope/cardinality enforced server-side, invalid layouts fall back
- Add quick checkin and duration input in H:M:S that round-trips integer seconds
- Fix heatmap/completedAt timezone drift to Asia/Shanghai
- Add server-side session TTL (30d) matching the login cookie
- Handle date.min/date.max boundaries without OverflowError
- Half-up rounding to match browser Math.round

 `data/tasks/<taskId>.json` 保存当前任务，`data/revisions/<taskId>/<revision>.json` 保存每次属性修订，`data/daily/<year>/<date>.json` 保存不可移动的每日事实，`data/archive/<year>/<month>.json` 是可重建汇总。任务 ID 和指标 ID 稳定，改名不会破坏历史。
 
-`metrics[]` 可同时含 `checkin`、`quantity`、`duration`；周期支持 `day`、`week`、`month`、`lifetime`；`target: null` 表示无上限，时长统一用整数秒。`config/layouts/home.json` 与 `task-detail.json` 只允许白名单组件，非法布局会回退到内置默认值。
+`metrics[]` 可同时含 `checkin`、`quantity`、`duration`；周期支持 `day`、`week`、`month`、`lifetime`；`target: null` 表示无上限，时长统一用整数秒。首页与任务详情按 `config/layouts/home.json` 与 `task-detail.json` 中的组件顺序渲染；布局只允许白名单组件，且每个组件限定其所属页面/区域，非法布局会回退到内置默认值。
 
 每日 0 点只关闭事实并重建归档，不删除原始记录。启动时会补跑遗漏日期；补录历史会触发对应月份重建。所有写接口带版本号冲突检测，任务删除默认为软删，后台可恢复或二次确认永久删除。
 
+进度统计只读原始每日事实、绝不读可重建的月归档：`/api/summary` 汇总全部任务、`/api/tasks/<id>/summary` 汇总单个任务，均按各指标自身的周期窗口（日/周/月/累计）聚合，累计窗口的下界取任务开始日期。会话在服务端带 30 天 TTL，与登录 Cookie 的 `max_age` 一致。

+## 已实现的实现细节（本次补充）
+
+- 进度统计只读原始每日事实、绝不读月归档；`/api/summary` 与 `/api/tasks/<id>/summary`
+  按各指标自身周期窗口聚合，`lifetime` 下界取任务开始日期，历史查询不会计入 `ref` 之后的事实。
+- 百分比采用与浏览器 `Math.round` 一致的四舍五入进位（half-up），避免 `.5` 边界不一致。
+- 布局组件按页面/区域约束（如 `task-header`/`today-record` 仅限任务详情页），非法组件不渲染。
+- 时长输入为「时:分:秒」，完整 round-trip 任意非负整数秒；一键打卡一次提交所有打卡指标。
+- 极端日期（`date.min`/`date.max` 附近的 month/week 窗口）不再溢出，返回 200。
