feat(desktop): release workflow + fix tauri build hooks (#205)

- beforeBuildCommand/beforeDevCommand run from the project root, not
  ui/ — use `yarn --cwd ui` so `tauri build`/`tauri dev` work again
- bundle.targets was [] which produces no artifacts; set "all" so
  each host OS emits its native bundles
- new desktop-release.yml: matrix build on ubuntu/windows/macos via
  tauri-action on `desktop-v*` tags — ships .msi/.exe, .dmg,
  .deb/.AppImage attached to the GitHub release
- ROADMAP Phase D updated to verified state

Verified locally on Linux: cargo test --workspace (49 tests) and
cargo tauri build -> Cloudreve_0.2.0_amd64.deb + .AppImage.

 |---|---|---|---|

 | Shell integration | shellext (keep) | Finder sync extension | Nautilus/Dolphin plugin (later) |
-| Notifications | win32_notif → replace | `tauri-plugin-notification` (all platforms) | same |
+| Notifications | win32_notif | `mac_notification_sys` | `notify_rust` |
 | Sync core | shared: `cloudreve-api`, `inventory`, `tasks`, `uploader`, `drive/sync` | same | same |
 
-- Port order: (1) strip `win32_notif`→tauri notifications (all platforms benefit), (2) abstract `drive/` behind a `HydrationProvider` trait (cfapi impl on Windows, stub→FUSE on Linux, FileProvider on macOS), (3) CI matrix build all 3, (4) MSIX→also ship .dmg/.AppImage/.deb.
+- Status: (1) notifications already per-OS (`win32_notif` / `notify_rust` / `mac_notification_sys`) — no abstraction needed; (2) hydration abstracted via `drive/placeholder` cfg swap — `cfapi` on Windows, `placeholder_non_windows` full-sync adapter elsewhere (FUSE / File Provider still open); (3) CI matrix builds + tests all 3 OSes; (4) packaging: `desktop-release.yml` on `desktop-v*` tags ships .msi/.exe (Windows), .dmg (macOS), .deb/.AppImage (Linux) — MSIX deferred (needs store signing).
+- Verified on Linux: `cargo test --workspace` green (49 tests), `cargo tauri build` produces working .deb + .AppImage.
 - Feature fallback on Linux/macOS until providers land: full sync without placeholders (download-on-access still works via sync engine).
