Add dev-app-update.yml so electron-updater can check GitHub releases
even when running with bun run dev. Remove the isPackaged guard from
checkForUpdates() so manual clicks always contact the update server.
Automatic periodic checks remain disabled in dev mode.

transitions to 'up-to-date' instead of reverting silently to 'idle'.
The troubleshooting UI shows a green check icon, 'Up to date' label,
and 'You are running the latest version of Aryx.' description.
