The Logos.Wallet QML plugin was installed with an ELF "$ORIGIN" rpath.
macOS dyld does not expand "$ORIGIN", so loading the plugin failed with
Cannot load library liblogos_wallet_qmlplugin.dylib:
Library not loaded: @rpath/liblogos_wallet_qml.dylib
even though liblogos_wallet_qml.dylib sits in the same directory. Select
the rpath per platform: @loader_path on Apple, $ORIGIN elsewhere, so
@rpath/liblogos_wallet_qml.dylib resolves to the sibling library.
