导入 XuXuCheck 工程(iOS 干化学尿液试纸分析 App)

从桌面工程复制而来,作为本仓库的 Xuxucheck/ 子目录。为控制仓库体积做了两处删减: - 移除 Frameworks/opencv2.xcframework 下的两个 visionOS 切片 (xros-arm64、xros-arm64-simulator,合计约 106 MB),并同步删掉该 xcframework 内 Info.plist 里对应的两条 AvailableLibraries 记录, 只保留 ios-arm64 与 ios-arm64_x86_64-simulator。 - 移除全部 .DS_Store 与 xcuserdata/。已用 xcodebuild 从本目录完整编译验证:BUILD SUCCEEDED, ProcessXCFramework 以 --platform ios 成功选中框架,产物含 3699 个 cv:: 符号 (OpenCV 确实链入),嵌入 framework 3 个,与移除无用 pod 之后的状态一致。仓库约 206 MB,其中 OpenCV 203 MB、其余源码与依赖约 3 MB。
