feat: 个人博客全栈实现（Rust/Axum + React/Tailwind + PostgreSQL）

后端（Axum + sqlx）：
- GitHub OAuth 三层权限（管理员/用户/游客），MOCK_OAUTH 本地调试开关
- 文章 CRUD、草稿自动保存、发布/私有分离，发布时渲染 HTML
- 目录（folder 路径分层）、标签、评论、RSS、热门文章（按评论数）
- pages 表驱动动态内容：关于页、首页标题、个人名片
- S3 兼容对象存储图片上传接口（rust-s3，未配置时明确报错）
- 发布时自动提取正文首图作为封面 cover_url
- sqlx migrate 管理 5 个迁移

前端（React + Tailwind）：
- 白天 Editorial / 黑夜星空双主题
- 首页（列表 + 热门侧栏 + 可编辑大标题）、文库（目录树+标签+搜索）
- Profile 页（GitHub 风格名片卡，全部字段后台可编辑）
- 后台：文件树文章管理、CodeMirror 编辑器（实时预览/自动保存/传图）
- Markdown 渲染：KaTeX 公式、代码块语言标注 + 双主题语法高亮
- 有封面的文章卡片自动整行展示，全局 ErrorBoundary

部署：
- docker-compose 本地三容器（postgres/backend/frontend）
- k8s manifests（适配 Caddy 终结 TLS → 隧道 → traefik 明文路由）
- 前端静态文件可由 Caddy 直接托管，集群只需 backend + postgres
- 可选 postgres 每日备份到 S3 的 CronJob
