feat(updater): Beta 渠道接通 auto-update（Builder.endpoints runtime 切换）

[appergb]

User description

Summary

CLAUDE.md 之前的论断「tauri-plugin-updater 2.10 Builder 不暴露 endpoints()」在 2.10.1 已不成立 —— Builder 现在有 .endpoints(Vec<Url>) -> Result<Self>，build() 里 self.endpoints.unwrap_or_else(|| self.config.endpoints.clone()) 走 runtime 覆盖。

本 PR 用这个新 API 接通 Beta 渠道的自动更新 —— 不 fork plugin、不写自定义下载/签名校验，复用 plugin 全部 plumbing。

What changed

Rust

• commands.rs::app_check_update_with_channel：
  • Stable → webview.updater_builder().build()?.check()（默认 endpoints 从 tauri.conf）
  • Beta → fetch_latest_beta_release() 拿最新 prerelease tag → 拼镜像 + 直连两份 -beta manifest URL → builder.endpoints(urls)?.build()?.check()
• AppUpdateMetadata 字段形状对齐 plugin 的 UpdateMetadata（rid + currentVersion + version + body + rawJson），前端 new Update(metadata) 即可复用 plugin 的 download / install / close。
• lib.rs 注册新 command。

前端

• AutoUpdate.tsx::checkForUpdates 从 import('@tauri-apps/plugin-updater').check 改为 invoke('app_check_update_with_channel')；其余 download / install / close 全走 plugin 原生 JS API。
• SettingsModal::BetaChannelControl 删掉「打开 GitHub 下载」按钮 —— auto-update 接管了，手动下载路径冗余；保留「最新 Beta 版本号 + 刷新」做信息透明。
• i18n 5 个 locale 改 betaChannelDesc 文案：「需要手动下载安装」→「自动接收最新 Beta 版本」。

物理隔离仍生效

Beta tag 的 manifest 文件名带 -beta 后缀（latest-{tgt}-{arch}-beta.json），跟 Stable 的 latest-{tgt}-{arch}.json 在 GitHub Release assets 里是分开的两份。即使代码逻辑错把 Beta URL 传给 Stable 用户也是 HTTP 404，不会拿到错档。

Test plan

• cargo test --lib -- --test-threads=1: 270 / 0 / 0
• npx tsc --noEmit exit 0
• npm run build clean
• 装包后手动验：Stable 用户走「检查更新」→ 拿 Stable manifest；切到 Beta toggle → 「检查更新」拿最新 Beta tag 的 manifest；切回 Stable → 回到 Stable manifest。
• 极端：Beta 渠道但还没发过任何 Beta release → check 返回明确错误「尚未发布过 Beta 版本」而非死循环。

⚡ Recommended focus areas for review Broken Mirror URL The beta mirror endpoint is built as ...-beta-mirror.json, while the direct endpoint uses ...-beta.json. Unless the release workflow also uploads a separate -beta-mirror.json asset, the first endpoint will always 404, so beta checks lose the intended mirror fallback behavior and add avoidable latency for users behind GitHub access issues. let mirror = format!("https://fastgit.cc/https://github.com/appergb/openless/releases/download/{tag}/latest-{{{{target}}}}-{{{{arch}}}}-beta-mirror.json");let direct = format!("https://github.com/appergb/openless/releases/download/{tag}/latest-{{{{target}}}}-{{{{arch}}}}-beta.json");
