fix(desktop): restore Linux launcher identity (#4649)

* fix(desktop): restore Linux launcher identity

Electron now derives Linux window identity from the scoped package name before app startup. Pin the existing Paseo.desktop identity in packaged metadata and check the built archive in the packaged-app smoke test.

* test(desktop): declare packaged smoke archive dependency

* fix(desktop): update Nix hash for smoke dependency
