taskUuid 在取消操作中完全未被消费，存在死代码风险。
经验证，当前 Ceph 后端（唯一实现该消息处理的后端）的 handle(CancelDownloadFileOnBackupStorageHostMsg) 实现中，taskUuid 字段虽然存在但从未被读取或使用。取消操作仅依赖 cancellationApiId，且在其为空时直接返回错误，不存在降级或优先级逻辑。
这与 GetFileDownloadProgressFromBackupStorageHostMsg 的语义不一致：后者明确要求 taskUuid 非空且在实现中活跃使用（第2340行），而取消消息中的 taskUuid 形同虚设。
建议：
- 若
taskUuid不适用于取消操作，应从消息类中删除，避免接口混淆。 - 若日后计划基于
taskUuid实现取消（如替代或补充cancellationApiId），应明确文档约定并一并实现相关逻辑。
