fix: TypeScript 适配器注释位置信息缺失导致 convert 失败

修复了 TypeScript 适配器在解析注释时未设置 StartCol 和 EndCol 的问题，
该问题导致 convert 命令无法正确替换注释内容，而是将英文注释添加到中文注释前面。

变更内容：
- 在 TypeScript 适配器中添加了 StartCol 和 EndCol 的设置
- 添加了 TestAdapter_Parse_Range 测试用例验证位置信息
- 验证了端到端的双向转换（中文↔英文）功能

测试：
- 所有单元测试通过
- 端到端测试验证了实际文件的正确转换
- 在 codei18n-vscode 项目上验证了修复效果
