joywayerandClaude Opus 4.7 0ecfa4fb69 修复 SplashImage 方向:素材逆时针旋转 90° 改为真正横屏
源素材 docs/res/Res/Default-568h@2x~iphone.png 是 CgBI PNG,物理 640×1136
但画面内容是"横躺"在竖向容器里 —— msext 旧 LaunchImage 系统依赖 device
orientation 自动旋转,现代 LaunchScreen.storyboard 没有这个魔法,直接显示
会看到躺倒的画面(用户反馈:启动图的横竖方向错误)。

处理:
- 用 sips -r -90 -s format png 一次性把素材逆时针旋转 90° 输出为标准
  PNG(顺便去掉 CgBI 优化标志),物理像素 1136×640,覆盖到
  ylgamehall/Assets.xcassets/SplashImage.imageset/SplashImage@2x.png
- LaunchScreen.storyboard 中 <image> 的 width/height 从 640/1136 改为
  1136/640;UIImageView 的 contentMode 从 scaleAspectFill 改为
  scaleAspectFit。aspectFit 在比 16:9 更宽的现代横屏 iPhone(如 16 Pro
  ≈2.17:1)上左右补黑边(黑底无视觉违和),保画面完整不裁切 logo
- WebContainer 的 SplashOverlay 用同款 scaleAspectFit,避免启动 → 容器
  视觉过渡时出现裁切方式跳变
- BuildProject 通过

Plan 进度已勾选(§5 Phase 1.14.b + §8 同步修订)
