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

+```
+
+## 快速开始
+
+### 1. 准备环境变量
+
+```bash
+cp .env.example .env
+# 编辑 .env，填入 GitHub OAuth 参数和你的 GitHub 用户 ID
+```
+
+### 2. Docker Compose 一键启动
+
+```bash
+docker compose up --build
+```
+
+访问：http://localhost
+
+后端 API：http://localhost:3000/api/health
+
+### 3. 本地开发
+
+启动 PostgreSQL：
+
+```bash
+docker compose up postgres -d
+```
+
+启动后端：
+
+```bash
+cd backend
+cargo run
+```
+
+启动前端：
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+## 权限模型
+
+| 角色 | 权限 |
+|------|------|
+| guest | 浏览公开文章、评论、标签、RSS |
+| user | guest 权限 + 发表评论 |
+| admin | user 权限 + 文章 CRUD、发布/私有、删除任意评论 |
+
+管理员通过 `GITHUB_ADMIN_ID` 环境变量指定，首次 GitHub 登录时自动赋予 `admin` 角色。
+
+## 编辑器工作流
+
+1. 管理员在 `/admin` 点击"新建文章"。
+2. 编辑器默认分屏模式：左侧 CodeMirror 编辑 Markdown，右侧实时预览。
+3. 输入停止 2 秒后自动保存草稿到后端 `drafts` 表。
+4. 点击"发布"：将草稿渲染为 HTML，状态变为 `public`。
+5. 已发布文章可转为 `private`（私有）或重新编辑。
+
+## API 概览
+
+### 公开接口
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | `/api/health` | 健康检查 |
+| GET | `/api/posts?page=&tag=&q=` | 公开文章列表 |
+| GET | `/api/posts/:slug` | 文章详情 |
+| GET | `/api/posts/:slug/comments` | 文章评论列表 |
+| GET | `/api/tags` | 标签云 |
+| GET | `/api/rss.xml` | RSS Feed |
+
+### 认证 / 用户 / 管理员接口
+
+详见 `backend/README.md`。
+
+## 部署到 k3s
+
+### 1. 构建并推送镜像
+
+```bash
+docker build -t your-registry/blog-backend:latest ./backend
+docker build -t your-registry/blog-frontend:latest ./frontend
+docker push your-registry/blog-backend:latest
+docker push your-registry/blog-frontend:latest
+```
+
+### 2. 修改 K8s 配置
+
+编辑以下文件中的占位符：
+
+- `k8s/backend/secret.yaml`：数据库连接串、JWT 密钥、GitHub OAuth 参数、管理员 GitHub ID
+- `k8s/postgres/secret.yaml`：PostgreSQL 密码
+- `k8s/backend/deployment.yaml`：`APP_URL` 和 `FRONTEND_URL`
+- `k8s/ingress.yaml`：你的域名
+- `k8s/kustomization.yaml`：镜像仓库地址
+
+### 3. 应用配置
+
+```bash
+kubectl apply -k k8s/
+```
+
+### 4. 网络说明
+
+你的场景是：**Caddy（TLS 终止）→ k3s Traefik（HTTP）→ frontend/backend**
+
+- 集群内 Ingress 使用 `traefik.ingress.kubernetes.io/router.entrypoints: web`（HTTP 80 端口）。
+- Caddy 负责 HTTPS 证书和终止 TLS，反向代理到集群的 80 端口。
+- 后端不做 TLS，不需要证书配置。
+- Ingress 中 `/api` 路径转发到 backend，其余路径转发到 frontend。
+
+## 安全注意事项
+
+1. **JWT_SECRET** 生产环境必须替换为随机强密钥。
+2. **GitHub OAuth state**：当前实现将前端 redirect URL 直接作为 state，存在开放重定向风险。后续建议对 state 做签名/加密。
+3. **Secret 管理**：当前用 K8s Secret 明文存储，生产建议使用 Vault / Sealed Secrets / External Secrets Operator。
+4. **PostgreSQL**：k3s 内使用 StatefulSet + PVC，建议配置定期备份（如 pg_dump CronJob 或 Velero）。
+
+## 后续可扩展
+
+- 接入对象存储（如 MinIO/S3）保存图片/附件。
+- 引入全文搜索（Meilisearch / Elasticsearch）。
+- GitHub Actions CI/CD 自动构建推送镜像。
+- 文章阅读量统计。
+- 评论通知 / Webhook。

+# React + TypeScript + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Oxc](https://oxc.rs)
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/)
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the Oxlint configuration
+
+If you are developing a production application, we recommend enabling type-aware lint rules by installing `oxlint-tsgolint` and editing `.oxlintrc.json`:
+
+```json
+{
+  "$schema": "./node_modules/oxlint/configuration_schema.json",
+  "plugins": ["react", "typescript", "oxc"],
+  "options": {
+    "typeAware": true
+  },
+  "rules": {
+    "react/rules-of-hooks": "error",
+    "react/only-export-components": ["warn", { "allowConstantExport": true }]
+  }
+}
+```
+
+See the [Oxlint rules documentation](https://oxc.rs/docs/guide/usage/linter/rules) for the full list of rules and categories.
