Replace the manual "jump to GitHub Release" update flow with native
in-app auto-update powered by electron-updater. The app now silently
downloads updates in the background and prompts the user to restart
when ready. Browser mode (`npm run dev`) retains the existing polling
fallback via `/api/app/updates`.
Main process (electron/updater.ts — new):
- Wrap electron-updater's autoUpdater, forward lifecycle events
(checking / available / downloading / downloaded / error) to the
renderer via IPC channel `updater:status`
- Register `updater:check` and `updater:quit-and-install` IPC handlers
- Auto-check 10s after launch, then every 4 hours
- Only initialized in packaged mode (!isDev)
Preload bridge (electron/preload.ts):
- Expose `updater` namespace with checkForUpdates, quitAndInstall,
and onStatus callback (same pattern as install.onProgress)
Type declarations (src/types/electron.d.ts):
- Add UpdateStatusEvent, ElectronUpdaterAPI interfaces
- Add optional `updater` field to ElectronAPI
Update hook (src/hooks/useUpdate.ts):
- Extend UpdateInfo with downloadProgress, readyToInstall, isNativeUpdate
- Add quitAndInstall to UpdateContextValue
Renderer — dual-mode logic (src/components/layout/AppShell.tsx):
- Detect `window.electronAPI?.updater` to choose between native IPC
subscription (Electron) and HTTP polling (browser)
- Map IPC events to UpdateInfo state, including download progress
UI components:
- UpdateDialog: three footer states — View Release (browser), progress
bar + disabled button (downloading), Restart to Update (ready)
- UpdateBanner (new): persistent top banner when update is downloaded,
shown even after dialog is dismissed
- NavRail: settings dot turns green + pulse when readyToInstall
- GeneralSection: UpdateCard shows download %, restart button, or
View Release depending on mode
Build & CI:
- electron-builder.yml: add `publish` config (github provider) to
generate latest-mac.yml / latest.yml metadata + blockmap files
- build.yml: change --publish never to --publish always with GH_TOKEN;
release job now uses `gh release edit` instead of create
i18n:
- Add 6 translation keys (en + zh) for update UI strings
