fix: 安全审查 P0-P2 问题修复（26项）

P0 关键修复：
- 移除 exit(0) 强制退出，改为应用语言设置后下次启动生效
- 修复 LivePhotoValidator hasResumed data race，引入线程安全 ResumeOnce
- 修复 addAssetID(toVideo:) continuation 泄漏，添加 writer/reader 启动状态检查
- 修复 OnboardingView "跳过" 按钮未国际化
- 修复 LanguageManager "跟随系统" 硬编码中文
- .gitignore 补全 AI 工具目录

P1 架构与 UI 修复：
- 修复 RealESRGANProcessor actor 隔离违规
- 修复 ODRManager continuation 生命周期保护
- TiledImageProcessor 改为流式拼接，降低内存峰值
- EditorView 硬编码颜色统一为设计系统
- ProcessingView 取消导航竞态修复
- 反馈诊断包添加知情同意提示

P2 代码质量与合规：
- EditorView/WallpaperGuideView 硬编码间距圆角统一为设计令牌
- PrivacyPolicyView 设计系统颜色统一
- HomeView 重复 onChange 合并
- PHAuthorizationStatus 改为英文技术术语
- Analytics 日志 assetId 脱敏
- 隐私政策补充 localIdentifier 存储说明
- 清理孤立的 subscription 翻译 key
- 脚本硬编码绝对路径改为相对路径
- DesignSystem SoftSlider 类型不匹配编译错误修复
