refactor(stage12): 调度域拆出 repository，跨域数据源改为显式注入

改动
- 新增 scheduling/repository.ts：通知/干预与建议列表的全部 SQL（13 条）。
- notify.ts / suggestions.ts 改为 register*(app, deps) 可注入，保留默认导出与 create*Router 工厂。
- suggestions.ts 的两处跨域依赖（里程车辆信息、OneOS 里程）改为依赖注入：
  既让本域可独立测试，也让"建议依赖里程数据"在类型上可见，而不是藏在 import 里。
- 跨域引用修正：mapRegion 原本从 '../vehicles/routes.js' 引入（为一个纯函数把整个
  车辆路由拖进依赖图），改为直接从 '../vehicles/model.js' 引入。

契约测试（新增 10 个用例）
- 逐条锁定 SQL 与参数顺序：干预登记的三步（查重 → INSERT → 回读）、409 阻断、
  批量循环、历史列表的状态过滤与 limit 上限（500/默认 200）、状态更新的 UPDATE 形状、
  400/404 分支、活跃映射与近 7 天计数、建议列表五条基础查询的内容与顺序。
- 架构守护升级：不再只看 routes.ts，而是要求该域**除 repository.ts 外的任何非测试文件
  都不得含 SQL**；匹配用"语句形状"正则（如 update <table> set）而非裸关键字，
  避免把 UpdateNotification 或日志 "update error" 误判。已验证 6/6 个 repository 被识别、
  其余文件零误判。

等价性验证
- 把 notify.ts / suggestions.ts 改造前的实现从 git 取出，与改造后跑同一批请求
  （9 个场景，含建议列表整条链路 8 次查询），对比落库 SQL、参数、HTTP 状态与响应体：
  完全一致。
- 期间修正了两处**验证工具自身**的缺陷（旧文件误引用新 notify；跨域默认实现的调用
  被记到另一侧），修正后结论可信。

lint / test(191) / build 全绿，可达性 0 未引用文件。
