feat: 添加前端项目基础配置和阶段示例

Browse Source 
添加 .editorconfig 配置文件用于统一编辑器设置，包括缩进风格、
换行符、字符集等规范。

添加 jsconfig.json 配置文件用于 JavaScript 项目的编译选项，
启用类型检查和模块解析配置。

添加 stage00 到 stage03 四个阶段的 HTML 和 JavaScript 示例：
- stage00: 基础 HTML 结构演示
- stage01: 纯命令式 DOM 操作实现用户卡片
- stage02: 声明式渲染方式重构用户卡片生成
- stage03: 扩展支持列表渲染多个用户数据

每个阶段都包含对应的 HTML 入口文件和 JavaScript 实现逻辑，
逐步展示从命令式到声明式渲染的演进过程。
