迁移：SPM → Xcode 构建，String Catalog 替代 .strings，清理 web/server/docker 废弃代码

- 项目从 SPM (Sources/VODManager/) 迁移到 Xcode 构建系统 (VODManager.xcodeproj) - 源码目录从 Sources/VODManager/ 迁移至 VODManager/VODManager/ - 用 Localizable.xcstrings 替代旧的 .lproj/Localizable.strings 文件 - 删除已废弃的 apps/web、apps/server、docker 目录及相关文档 - RTL 侧边栏修复：切语言时用 .id() 强制重建 NavigationSplitView - 视频库无账号时不发起 API 请求和重试 - 无账号时显示 ContentUnavailableView 提示

-# 火炬 VOD 管理器 - macOS 原生版
-
-基于 SwiftUI + Swift Package Manager 的阿里云 VOD 桌面管理客户端。
-
-## 特性
-
- 原生 macOS SwiftUI 界面
- 直接调用阿里云 VOD OpenAPI，无需 Node 后端
- 多账号管理、切换
- 视频列表、搜索、详情
- 批量下载到用户指定目录
- 自定义下载文件名（自动清理非法字符）
- 下载任务历史
- 操作日志
-
-## 技术栈
-
- Swift 6 + SwiftUI
- GRDB（SQLite）
- CryptoKit（阿里云 POP 签名）
- URLSession（网络请求与下载）
-
-## 开发要求
-
- macOS 14+
- Xcode 15+
- Swift 5.9+
-
-## 本地运行
-
-```bash
-cd apps/macos/VODManager
-swift build
-swift run
-```
-
-或在 Xcode 中打开 `Package.swift`。
-
-## App Store 上架准备
-
-1. 在 Xcode 中创建正式的 macOS App 工程（或打开 Swift Package）。
-2. 配置 Signing & Capabilities：
-   - App Sandbox 开启
-   - 启用 entitlements 文件 `VODManager.entitlements`
-   - Team 与 Bundle Identifier
-3. 提交 Mac App Store 审核。
-
-### Entitlements 说明
-
- `com.apple.security.app-sandbox`：沙盒必须开启
- `com.apple.security.network.client`：访问阿里云 API
- `com.apple.security.files.user-selected.read-write`：用户选择下载目录
- `com.apple.security.files.downloads.read-write`：写入 Downloads 目录
-
-## 与 Web 版的关系
-
-Web 版（`apps/web` + `apps/server`）已废弃，不再维护。所有新功能在 macOS 原生版中实现。
