优化 Excel 数据处理和命令发送逻辑

- 修改 `Excel2Prompt.cs` 中 `ConverterToPrompt` 方法,支持列名映射。
- 提取 `AiMessageControll.xaml.cs` 中的发送命令逻辑到 `InvokeSendCommand` 方法。
- 在 `ImportViewModel.cs` 中新增 `_columnMappings` 字典,增强 Excel 数据处理逻辑。
- 整合并简化 `GenColumns` 方法的实现。
- 新增 `StringExtensions` 静态类,提供字符串替换扩展方法。
- 更新 `launch.json` 和 `tasks.json`,新增调试和构建配置。
