feat: add version option to command line parser

1. Added version option to QCommandLineParser in main.cpp to display
version information
2. Removed DVERSION from debian/rules configuration as it's no longer
needed
3. Maintained DTK_VERSION setting in build configuration

The changes improve command line interface by adding standard --version
flag support while simplifying the build configuration by removing
redundant version setting.

feat: 为命令行解析器添加版本选项

1. 在 main.cpp 中为 QCommandLineParser 添加版本选项以显示版本信息
2. 从 debian/rules 配置中移除不再需要的 DVERSION 参数
3. 保留构建配置中的 DTK_VERSION 设置

这些改动通过添加标准的 --version 标志支持改进了命令行界面，同时通过移除
冗余的版本设置简化了构建配置。
