chore: add qt6-tools-dev to build dependencies

Added qt6-tools-dev to the Build-Depends section in debian/control
file. This change is necessary because the project now requires Qt6
development tools for building, likely due to new features or build
processes that depend on Qt6 tooling utilities.

Influence:
1. Verify the package builds successfully with the new dependency
2. Test that all Qt6-related tools are available during build
3. Check that no build errors occur related to missing Qt6 tools
4. Ensure cross-platform compatibility is maintained

chore: 在构建依赖中添加 qt6-tools-dev

在 debian/control 文件的 Build-Depends 部分添加了 qt6-tools-dev。此变更
是必要的，因为项目现在需要 Qt6 开发工具进行构建，可能是由于新功能或构建
过程依赖于 Qt6 工具链实用程序。

Influence:
1. 验证包是否能够使用新依赖成功构建
2. 测试构建期间所有 Qt6 相关工具是否可用
3. 检查是否出现与缺失 Qt6 工具相关的构建错误
4. 确保跨平台兼容性得以保持
