docs: 开始翻译Go代码中的中文注释和字符串

🌍 代码国际化第一阶段:
- docs/package.json - 翻译项目描述为英文
- examples/01-basic-usage/main.go - 完全翻译为英文
- examples/08-position-aware-editor/main.go - 部分翻译

✅ 翻译内容:
- 代码注释翻译为英文
- 输出字符串翻译为英文
- 错误消息翻译为英文
- 保持代码逻辑和功能不变

🎯 用户体验:
- 示例代码对国际用户更友好
- 输出信息清晰易懂
- 符合国际开源项目标准

📝 进度:
- 已完成: 2个重要示例文件
- 待处理: 其他examples和pkg目录下的文件

这是代码国际化的第一步，确保用户看到的
示例代码和输出都是英文的。
