refactor: 项目架构重构 - 目录标准化 + 清理冗余

- 目录重命名: backend/wdkj-server/ → server/, frontend/ai-dimension/ → client/ - 删除 20+ 冗余文件（WDKJ 旧脚本、Windows 脚本、过时文档、设计稿） - 更新 package.json 元数据（移除 wdkj 命名） - 完善三级 .gitignore（根 + server + client） - 重写 README.md 和 CHANGELOG.md - 工具脚本移至 scripts/

-
-## 快速开始
-
-### 1. 安装依赖
-
-```bash
-cd wdkj-server
-npm install
-```
-
-### 2. 配置环境变量
-
-复制 `.env.example` 为 `.env` 并修改配置：
-
-```env
-# 服务配置
-PORT=3000
-NODE_ENV=development
-
-# MongoDB 配置
-MONGODB_URI=mongodb://wdkj123:wdkj123@192.168.136.130:27017/wdkj?authSource=wdkj
-
-# JWT 配置
-JWT_SECRET=your_secret_key_here
-JWT_EXPIRE=7d
-
-# 微信小程序配置
-WX_APPID=wxdad62baf4ccd09e3
-WX_SECRET=your_wx_app_secret
-
-# 微信支付配置
-WX_PAY_MCH_ID=1108945993
-WX_PAY_API_KEY=your_apiv3_key
-```
-
-### 3. 启动服务
-
-```bash
-# 开发环境
-npm run dev
-
-# 生产环境
-npm start
-```
-
-### 4. 验证服务
-
-访问健康检查接口：
-
-```bash
-curl http://localhost:3000/health
-```
-
-## API 文档

-## 数据库初始化
-
-首次启动服务时，需要初始化管理员账户：
-
-```javascript
-// 可以创建一个初始化脚本
-const Admin = require('./src/models/Admin')
-
-async function initAdmin() {
-  const admin = new Admin({
-    username: 'admin',
-    password: 'admin123456',
-    email: 'admin@wdkj.com',
-    role: 'super_admin',
-    permissions: ['*']
-  })
-  await admin.save()
-}
-```
-
-## 开发指南
-
-### 代码规范
-
- 使用 ES6+ 语法
- 异步操作使用 async/await
- 错误统一通过 ApiResponse 处理
- 所有操作记录日志
-
-### 日志系统
-
-日志级别：
- `debug`: 调试信息
- `info`: 常规信息
- `warn`: 警告信息
- `error`: 错误信息
-
-使用示例：
-
-```javascript
-const logger = require('./utils/logger')
-
-logger.info('用户登录', { openid: 'xxx' })
-logger.error('数据库错误', error)
-```
-
-### 权限系统
-
-角色权限矩阵：
-
-| 角色 | 权限范围 |
-|------|----------|
-| super_admin | 所有权限 (*) |
-| content_manager | 知识库、画廊、用户查看 |
-| shop_manager | 商品、订单、用户查看 |
-| viewer | 仪表盘、分析、用户查看 |
-
-## 生产部署
-
-### 使用 PM2
-
-```bash
-# 安装 PM2
-npm install -g pm2
-
-# 启动服务
-pm2 start src/index.js --name wdkj-server
-
-# 查看状态
-pm2 status
-
-# 查看日志
-pm2 logs wdkj-server
-```
-
-### 使用 Docker
-
-创建 `Dockerfile`:
-
-```dockerfile
-FROM node:18-alpine
-WORKDIR /app
-COPY package*.json ./
-RUN npm ci --only=production
-COPY . .
-EXPOSE 3000
-CMD ["npm", "start"]
-```
-
-构建并运行：
-
-```bash
-docker build -t wdkj-server .
-docker run -p 3000:3000 -d wdkj-server
-```
-
-## 注意事项
-
-1. **安全**: 生产环境必须修改 JWT_SECRET
-2. **数据库**: 确保 MongoDB 已正确配置访问权限
-3. **支付**: 微信支付需要真实的商户证书和密钥
-4. **日志**: 生产环境会自动写入日志文件
-5. **限流**: 已配置 API 请求频率限制

-# 后端 API 评估与改造计划
-
-## 现有 API 与新前端映射
-
-### ✅ 可直接复用
-
-| 前端功能 | 后端 API | 改造量 |
-|---------|---------|--------|
-| 微信登录 | `POST /api/auth/login` | ✅ 零改动 |
-| H5 注册/登录 | `POST /api/auth/user/register` / `POST /api/auth/user/login` | ✅ 零改动 |
-| 获取用户信息 | `GET /api/auth/me` | ✅ 零改动 |
-| 知识列表（按维度） | `GET /api/knowledge?dim=1&category=concept` | ✅ 零改动，改数据即可 |
-| 知识详情 | `GET /api/knowledge/:id` | ✅ 零改动 |
-| 收藏/取消收藏 | `POST /api/knowledge/:id/collect` / `DELETE /api/knowledge/collect/:id` | ✅ 零改动 |
-| AI 问答 | `POST /api/ai-chat/ask` | ⚠️ 改 system prompt（从几何→AI） |
-| 问答配额 | `GET /api/ai-chat/quota` | ✅ 零改动 |
-| 分享获得次数 | `POST /api/ai-chat/share-gain` | ✅ 零改动 |
-| 创建订单 | `POST /api/payment/create-order` | ✅ 零改动 |
-| 商品列表 | `GET /api/payment/products` | ✅ 改商品数据 |
-| 提交反馈 | `POST /api/feedback` | ✅ 零改动 |
-| 上传作品 | `POST /api/gallery` | ⚠️ 改为 AI 作品展示 |
-| 作品列表 | `GET /api/gallery` | ✅ 零改动 |
-
-### ⚠️ 需改造
-
-| API | 改动内容 | 工作量 |
-|-----|---------|--------|
-| `POST /api/ai-chat/ask` | `getSystemPromptByDimension()` 函数 — 从几何 prompt 改为 AI 主题 prompt | 改 1 个函数 |
-| `GET /api/user/progress` | 原为几何探索进度，改为 AI 学习进度 | 前端改字段名即可 |
-| `POST /api/user/progress` | 同上 | 前端改字段名即可 |
-
-### ❌ 移除或降级
-
-| API | 处理方式 |
-|-----|---------|
-| `GET /api/pinyin/*` （4 个路由） | 前端不调用即可，后端保留兼容 |
-| `GET /api/bgm` | 可作为可选功能保留（背景白噪音） |
-| `GET /api/share` | 保留，用于分享激励 |
-
-## 需要新增的 API
-
-| 新 API | 说明 | 工作量 |
-|--------|------|--------|
-| `GET /api/trends` | AI 趋势资讯列表（接入 Hermes cron 的新闻数据） | 新建 model + route，1天 |
-| `GET /api/tools` | AI 工具导航列表 | 简单 CRUD，小时级 |
-
-## 改造总结
-
-**后端改造成本极低，95% 的 API 可以直接用。**
- 主要改 1 个函数（AI Chat system prompt）
- 新增 1-2 个接口（趋势、工具）
- 其余全部零改动
-
-## 数据库改造
- 无需改 schema
- Knowledge 表已有 `dim`, `category`, `sections`, `tags`, `isPremium` 等字段
- 只需填充 AI 内容数据
- AIChatQuota 表可以直接用（原 5 次免费 → 改为 10 次免费）
