feat(vqt6): 信号槽回调机制 + 高层包装类扩展

Browse Source 
- 信号槽：vqt6_signal_register/trigger_slot 锁外回调，覆盖 QPushButton/QCheckBox/QRadioButton/QLineEdit/QComboBox/QSlider/QSpinBox/QProgressBar/QListWidget/QTabWidget/QAction/QTimer 共 13 个信号
- 高层包装：新增 QMainWindow/QDialog/QLineEdit/QCheckBox/QRadioButton/QComboBox/QSlider/QSpinBox/QProgressBar/QTextEdit/QPlainTextEdit/QListWidget/QTabWidget/QStackedWidget/QHBoxLayout/QVBoxLayout/QGridLayout/QMessageBox/QFileDialog/QTimer/QMenuBar/QMenu/QAction/QStatusBar/QColor/QFont 等 26 个类
- 便捷 FFI：vqt6_qlabel_set_text_utf8 / vqt6_qplaintextedit_append_utf8（Viper str 直传，避免 QString 手动管理）
- 修复：QApplication 构造需 int& 左值（dummy_argc）；QCheckBox 用 checkStateChanged 避免弃用警告
