Both approaches fail — redox-toolchain.cmake overrides include paths.
Root cause: Qt6 cmake configs from qtdeclarative (built with qml_jit=OFF)
do not export Qt6Qml/Qt6Quick include directories properly for downstream
consumers. Headers exist at /usr/include/QtQml/QQmlEngine but cmake does
not add -I paths. This is the precise QML gate mechanism.
