Remove redundant Qt6 migration comments that restate obvious API changes: - QtConcurrent::run parameter order explanations (preserved where lambda wrapping needed) - QStringRef/QStringView API changes (shortened to essential info) - QComboBox::activated signal signature change - QMap::unite() removal semantics - QAction include path change - QMouseEvent/QWheelEvent position() API - QList/QVector equivalence in Qt6 - QFuture continuation API - Code generation comments Preserved comments explaining non-obvious Qt6 behavior or necessary API migration details.
