📝 Walkthrough

Walkthrough

This PR adds a comprehensive automatic update system to the desktop application. It introduces an UpdateManager service that handles checking, downloading, and applying updates from GitHub releases, integrates it into the application runtime, exposes update operations through RPC handlers, and updates the Settings UI with auto-update toggles and update status controls.

Changes

Cohort / File(s)	Summary
Type definitions and RPC schema apps/desktop/src/shared/types.ts, apps/desktop/src/shared/rpc.ts	Added AppUpdateStatus and AppUpdateState types to model update lifecycle states; extended AppRPCSchema with four new RPC endpoints: setAutoUpdate, getUpdateState, checkForUpdates, and applyUpdate.
Update manager and runtime integration apps/desktop/src/bun/utils/update-manager.ts, apps/desktop/src/bun/runtime.ts	Introduced UpdateManager class that orchestrates update state, checks for updates with connectivity verification, downloads updates, and applies them; integrated it into AppRuntime with initialization and accessor methods.
RPC handler and client layer apps/desktop/src/bun/rpc.ts, apps/desktop/src/mainview/lib/rpcClient.ts	Added RPC request handlers in the Bun process that delegate to UpdateManager; added corresponding RPC client methods in the frontend for invoking update operations.
Frontend update UI and hooks apps/desktop/src/mainview/hooks/useUpdates.ts, apps/desktop/src/mainview/screens/Settings.tsx	Introduced useUpdateState and useUpdateActions React Query hooks; refactored Settings component to display update status, auto-update toggle, and contextual update/install buttons with error handling.
Configuration and infrastructure .github/workflows/release.yml, apps/desktop/electrobun.config.ts, apps/desktop/src/bun/index.ts, apps/desktop/src/bun/utils/engine-manager.ts	Updated GitHub release workflow to upload all artifacts from apps/desktop/artifacts/*; added release.baseUrl config pointing to GitHub releases; triggered auto-update on application launch; redirected engine binary URLs from Vercel to GitHub releases.

🐰 A rabbit's wish, now update complete,
With GitHub releases, so neat and sweet,
Auto-updates hop along with care,
No stale versions anywhere,
Fresh as lettuce, always fair! 🥬
