M0：项目基础配置就绪（横屏锁定、Swift 6、代码启动）

- 锁定 iPhone/iPad 仅横屏（LandscapeLeft/Right），契合 H5 端
  1280×720 设计分辨率；UIRequiresFullScreen=true 防 iPad
  多任务下方向不锁
- Swift Language Version 升到 6.0（配合已启用的
  Approachable Concurrency + MainActor 默认隔离）
- 删除默认 Main.storyboard / ViewController.swift 模板，
  改用 SceneDelegate 代码创建 RootViewController 启动，
  Build Settings 同步清空 INFOPLIST_KEY_UIMainStoryboardFile
- Info.plist 补齐契约项 UIStatusBarHidden=NO、
  UIViewControllerBasedStatusBarAppearance=YES，配合
  AppDelegate 启动时设置 applicationSupportsShakeToEdit=true
  覆盖契约 §4.2.1 摇一摇前置
- BuildProject 通过验证
