build-launcher.bat: publishes PSLauncher.App only (Release single-file).
build-updater.bat: publishes PSLauncher.Updater only.
build-all.bat: both, sequentially, fast-fail on the first error.
All three pause at the end so a double-click from Explorer shows the
result before the window closes. The existing build-installer.bat
(launcher + updater + Inno Setup .exe) stays as the full release
pipeline.
