- 修改清理逻辑跳过锁文件和下载中的临时文件
- 添加测试验证缓存锁功能正常工作

fix(ffmpeg): 优化FFmpeg命令执行和错误处理

- 添加默认日志级别为error减少冗余输出
- 修复subprocess运行参数传递方式
- 改进错误信息截取避免空值解码异常

refactor(system-info): 优化系统信息获取和缓存机制

- 实现FFmpeg版本、编解码器信息缓存避免重复查询
- 添加系统信息TTL缓存机制提升性能
- 实现GPU信息检查状态缓存避免重复检测
- 整合静态系统信息和动态信息分离处理

refactor(storage): 优化HTTP上传下载资源管理

- 使用上下文管理器确保请求连接正确关闭
