Subject: [PATCH] feat: embed AppImage update information for delta updates

Add a top-level publish config in electron-builder.json5 pointing to
GitHub Releases. This embeds the update information URL in the AppImage
header, enabling tools like AppImageUpdate, AppImageLauncher, and
AppManager to perform delta updates instead of full re-downloads.

Also update the Linux build workflow to upload the generated .zsync file
alongside the .AppImage artifact.

Fixes #219
