Make GUI installer publish as single-file self-contained exe

The GUI installer was missing from v1.3.0 release because the publish
step produced 280 loose files but only the exe was copied to the release
zip. Without its DLLs, the exe would crash on launch.

Add PublishSingleFile, SelfContained, and related properties to match
the CLI installer csproj. Remove now-redundant flags from build.yml.
