The MSI had no UI, so Windows Installer showed only its basic progress box and closed
without saying the install had worked. It now uses WiX's standard WixUI_Minimal dialogs:
a welcome page with the license (MIT or Apache-2.0, built at packaging time from
LICENSE-MIT and LICENSE-APACHE), progress, and a finish page with an optional
"Launch WordCraft" checkbox. The release and Windows ARM64 workflows install the WiX
UI and Util extensions the build now needs. UpgradeCode and component GUIDs are unchanged.
