 # 从旧清单迁移到 manifest v3

 1. 添加 `manifestVersion: 3`、`apiVersion: "2"` 和 `runtime: "WebView"`。
 2. 为 `permissions` 中每项权限添加非空 `permissionReasons`。
 3. 将启动必需权限放入 `security.requiredPermissions`，其余保持可选。

 `WebView` 是默认和正式运行时。Tauri 独立窗口仅使用应用自带宿主，默认关闭；它要求插件开发者模式、`ExternalRuntime` 授权和按插件版本保存的二次确认。Tauri 插件内容运行在独立的 `https://p-<hash>.localhost` 原点和插件私有 WebView2 数据目录中，应用宿主页只通过一次性、当前用户命名管道把 Bridge 请求转发给同一个权限宿主。会话令牌仅存在于原生宿主内，不进入插件 JavaScript。插件包不能携带或构建原生可执行文件，也不能访问 Tauri 全局 API。
