feat(hardening): 内嵌产品配置 + 系统级状态 + 全量 i18n + 依赖治理 + 资料清理

update-client-hardening 四工作流合入（构建/静态检查已过）： - 配置：不可变产品策略经 UpdateClientResources.cmake 归一化校验后内嵌 qrc（URL/相对路径/主程序必须落 install_root/版本/UUID 格式， CMake override 写入前复验）；可变机器状态迁系统级原生存储；运行目录不再落可编辑 app_config.json。 - i18n：生产源全英文（no-Han 检查 41/41），中文进 translations/ zh_CN 目录；翻译加载收敛 Common/TranslationHelper 唯一入口； Bootstrap 补资源文件。 - 依赖：Qt/OpenSSL/架构/Perl 机器路径改 imported targets + UpdateClientDependencies.cmake，3rdparty 由父工程契约供给。 - 清理：旧 README/SDK README/3 个重复 PowerShell 打包脚本/PDF 提取文本删除，canonical README + 5 份结构化英文文档替代；Launcher requireAdministrator manifest；统一 MSVC /utf-8 删运行时编码设置。
