Merge branch 'chore/remove-recent-module'

- FileLibRecentVisit 删表(手写迁移;表当日新建无生产数据)
- recentService/recentRoutes/RecentView 删除;GridLibraryView 埋点与
  navTarget 跳转一并移除;types 清 RecentEntry
- 左栏保留 文件库/回收站(ADR-0031 回收站半部不受影响)
- breadcrumb 的 role 字段保留(独立可用的增量字段)

+# ADR 0032: Remove The Recent-Visit Module
+
+## Status
+
+Accepted. **Supersedes the "Recent visits" half of ADR-0031** (the recycle-bin half
+is unaffected and remains in force).
+
+## Context
+
+ADR-0031 (same day) introduced 最近打开: a `FileLibRecentVisit` table, client-driven
+visit recording, and a rail entry in the teacher app. After seeing it live, the product
+call is that the module is not wanted — it adds a tracking surface, a table, and rail
+noise without a compelling teacher workflow behind it.
+
+## Decision
+
+The recent-visit module is removed end-to-end:
+
+- `FileLibRecentVisit` is dropped (hand-written migration
+  `20260731090000_drop_filelib_recent_visit`; the table was created the same day and
+  held no production data).
+- `recentService` / `recentRoutes` (`/database/api/recent`) and the `RecentView`
+  component are deleted; the rail in `/app` keeps only 文件库 / 回收站.
+- `GridLibraryView` visit recording and the `navTarget` navigation entry go with it.
+- The `role` field added to breadcrumb entries for ADR-0031 is **kept** — it is a
+  cheap, additive field on an existing API and independent of the removed module.
+
+If recent-visit tracking comes back as a requirement, it is a new decision (and
+should then define why client-driven tracking is worth its surface) rather than a
+revival of this one.
