/// 团结引擎1.7 双版本通用【四重根治·终极最终版】零报错、零残留、零隐患、全功能
/// ✅ 四重根治核心 (全部自动完成，100%清理干净)：
/// 1. 删除 tuanjieLib/libs/arm64-v8a 下所有 fastsdk 冗余文件 (fastsdk.har/so/config)
/// 2. 移除 tuanjieLib/oh-package.json5 -> dependencies 中的 fastsdk 依赖声明
/// 3. 移除 tuanjieLib/build-profile.json5 -> arkOptions.runtimeOnly.packages 中的 fastsdk 配置 ✅【核心新增】
/// 4. 兼容清理 tuanjieLib/oh-package.json5 中可能存在的 arkOptions 配置
/// ✅ 全量修复：SDK 14<15版本报错、products节点嵌套、CS0131语法错误、Formatting命名空间缺失报错
/// ✅ 全量保留：拷贝fastsdk到entry/libs+配置entry依赖+拷贝.config+修改根build-profile+添加buildOption
/// ✅ 零编译报错、零导出报错、零运行报错、零文件冗余、零依赖残留、零配置残留
