// cxx-qt-build emits a QQmlEngineExtensionPlugin C++ class with Q_PLUGIN_METADATA
// alongside an `init_cxx_qt_qml_module_<name>_plugin()` symbol whose only purpose is
// to anchor that translation unit. Without referencing it from Rust, the linker
// drops the .o containing the plugin class - Qt then dlopens the .so, finds no
// plugin metadata, and never calls qml_register_types_NovaStats.
