Add native installer packaging to CI for all platforms

Linux: DEB with /opt/wowee prefix and /usr/local/bin/wowee wrapper script
Windows x86-64: NSIS installer with DLL bundling and Start Menu shortcut
Windows ARM64: ZIP archive with bundled DLLs
macOS ARM64: .app bundle via dylibbundler + DMG via hdiutil

Assets are bundled into all packages (Original Music excluded). StormLib
is installed where available so asset_extract is included in packages.
