Wine runs the test binary cleanly when targeting x86_64-pc-windows-gnu,
so wire that target's runner to wine in .cargo/config.toml. The default
windows-msvc build is unaffected.
README gains a 'Linux Cross-Build (Optional)' section with the dotnet
10 / mingw-w64 / wine prerequisites and the EnableWindowsTargeting=true
recipe needed to cross-build the net8.0-windows C# UI from Linux.
