fix: 暂时禁用 system-stats validation 功能以修复编译错误

问题：
- proxy.rs 调用 validate::run_validation
- validate.rs 导入 SystemStatsResponse 的路径在不同的二进制模块中不同
- 导致编译错误

临时修复：
- 注释掉 proxy.rs 中对 validate 模块的调用
- 在 system-stats API 中直接返回 stats 数据，不进行 validation
- 保持基本功能可用

未来改进：
- 需要重构模块结构，使 SystemStatsResponse 在所有模块中都可访问
- 或者使用条件编译处理不同的导入路径
