feat(desktop): tray + lancement au login + auto-update (C5)

tray.ts : icône de barre système (Ouvrir, bascule « Launch at login », Quitter). autostart.ts : login items (Windows/macOS) + fichier ~/.config/autostart/*.desktop (Linux). updater.ts : electron-updater (provider generic -> release Gitea), no-op en dev, actif Windows/Linux. main.ts : fermeture de fenêtre = réduction dans le tray, quit explicite via tray/menu, arrêt propre du daemon avant sortie.

icon.png ajouté aux extraResources (tray en packagé). Vérifié : typecheck contre l'API Electron + electron-updater, bundle esbuild.
