Add desktop (Electron) packaging and release distribution (#1147)

* Add desktop packaging workflow

* Add desktop package homepage

* Fix desktop default credential prompt

* Suppress default credential prompt on desktop

* Publish desktop artifacts on release; reduce CI to PR smoke test

Add desktop-release.yml triggered on release publish (mirroring
docker-publish.yml) to build all platforms and upload .dmg/.exe/
.AppImage/.deb to the GitHub Release.

Trim build.yml desktop job to a PR-only Linux x64 smoke test, since
release artifacts are now produced by desktop-release.yml. This drops
per-push and macOS/Windows packaging from regular CI.
