Fix macOS release packaging to use proper .app bundle structure (#51)

macOS builds were shipping as flat folders of DLLs/binaries that weren't
runnable. Now creates a proper .app bundle (Contents/MacOS, Contents/Resources,
Info.plist) so the app is double-clickable on macOS.

Also adds missing CFBundleExecutable to Info.plist and auto-syncs the
plist version from the csproj at build time so it can't drift.
