feat: remove debian/compat file

Removed the debian/compat file which specified the Debian packaging
compatibility level as 12. This file is no longer needed as the
project's packaging requirements have changed or the compatibility
level is now managed differently, possibly through other packaging tools
or configurations. This cleanup simplifies the package structure and
removes unnecessary files.

Influence:
1. Verify Debian package builds successfully without the compat file
2. Test that packaging tools handle the missing compat file correctly
3. Ensure no regression in package installation or dependency resolution
4. Confirm that the package still meets Debian policy requirements

feat: 移除 debian/compat 文件

删除了指定 Debian 打包兼容性级别为 12 的 debian/compat 文件。由于项目的
打包需求已发生变化，或者兼容性级别现在通过其他打包工具或配置进行管理，该
文件不再需要。此次清理简化了包结构并移除了不必要的文件。

Influence:
1. 验证 Debian 包在没有 compat 文件的情况下是否成功构建
2. 测试打包工具是否正确处理缺失的 compat 文件
3. 确保包安装或依赖解析没有出现回归问题
4. 确认包仍然符合 Debian 政策要求
