feat(ssr): 真 SSR 收尾——干净 hydration 与浏览器原生滚动恢复

- 修复 onRenderClient 引入 serverClient 导致浏览器 process is not defined：抽出双端安全的 ssr/feedSeed.ts 作为唯一数据播种入口，serverClient 加 SSR 守卫 - 修复 React 19 Fizz Suspense Outlining：Suspense 边界从布局 Outlet 下移到各懒加载路由，SSR 输出不再出现  / $RB / template 探针标记 - 修复窄屏 React #418 hydration 致命错误：useMediaQuery 首帧恒 false， useLayoutEffect 绘制前同步真实值；主题改 cookie 存储供 SSR 直出， head 内联防闪烁/缩放脚本移除（缩放锁改为客户端 zoomGuard 模块） - 清理假 SSR 残留：删除 StaticFeedList 镜像组件、SSR 图标生成脚本、探针与死代码；列表接口裁剪正文，仅下发 excerpt/first_image - Feed 与帖子详情改为窗口滚动（app-shell--doc-scroll）：删除虚拟列表、自研滚动快照与全局滚轮 hack；F5/前进后退滚动位置全部交给浏览器原生历史恢复，HTML 响应头 no-cache 配合；锚点/楼层用 scrollIntoView + scroll-margin-top 适配 sticky 顶栏
chore: Tailwind CSS 3.4 迁移到 4.x（CSS-first 配置 + @tailwindcss/vite）

- **单二进制** — `go:embed` 打包前端，无需再单独部署静态资源
+- **双服务架构** — Node（:3000 对外：SSR + 静态资源 + API 反代）+ Go（:3001 内部：纯 API），职责单一、可独立扩缩
+- **服务端渲染** — 首页 / 板块 / 帖子详情由 Vike SSR 真渲染，SEO 友好、首屏直出；其余页面 SPA 接管
 - **零依赖数据库** — SQLite 内建，数据目录由 `app.ini` 统一管理
- **跨平台** — Windows / Linux / macOS 一键编译
+- **跨平台** — Windows / Linux / macOS 一键编译 Go API
 - **系统服务** — 内置 Linux systemd / Windows Service 注册
- **Docker 单容器** — 多阶段镜像，挂载 `data/` 即可持久化
+- **Docker 双容器** — 同一镜像两种角色，`docker compose up` 一键起
