解决iPadOS 16 Stage Manager下应用强制全屏问题

UIRequiresFullScreen在iPadOS 16中对Stage Manager的约束逻辑已调整，仅设置该键无法完全让应用排除在Stage Manager之外，需配合以下Info.plist配置：
- 将UIApplicationSceneManifest下的UIApplicationSupportsMultipleScenes设为NO
- 添加UIApplicationSceneManifest -> UISceneManifestPrefersSingleScene并设为YES，明确告知系统应用仅支持单场景模式
- 检查UISceneConfigurations -> UIWindowSceneSessionRoleApplication下的场景配置，确保未启用多场景相关选项

若仍有问题，可在代码层面强制窗口锁定全屏（以Swift为例，SceneDelegate中）：

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = scene as? UIWindowScene else { return }
    let window = UIWindow(windowScene: windowScene)
    window.rootViewController = YourRootViewController()
    self.window = window
    window.makeKeyAndVisible()
    // 锁定窗口尺寸为屏幕大小，禁止缩放
    windowScene.sizeRestrictions?.minimumSize = windowScene.screen.bounds.size
    windowScene.sizeRestrictions?.maximumSize = windowScene.screen.bounds.size
}
