建议你同步一下上游，现在上游的目录结构有比较大的改变 |

存在几个问题：
- 应该存在一个全局共用的线程数限制
- 应当支持处理多个文件和多次提交，并复用已有的 DownloadClient 实例，一个下载任务很可能包含一大批文件且可能先后多次提交，它们要与已存在的所有任务共享全局线程数限制，在有必要的时候需要排队机制
- HttpClient 应使用传入 getter delegate 的方式获取，每次下载均创建一个 HttpClient 会导致大量小文件下载时初始化时长远大于实际数据传输时长，极其影响性能
- 需要支持持久化 mirror 数据，因为一个 mirror 的质量在一个用户那里大概率是一直相同的，每次都收集数据并动态决策本身就是很耗时的操作了（因此也引出了新的问题：需要考虑更复杂更全面的 mirror 评估算法）
- 测试明显像 AI 写的，代码的 AI 参与度比较存疑，这点需要一个明确解释

测试懒得写，直接丢给AI让他写了（
这个PR只是一个底层的部分，我计划把这个作为上层部分来实现（DownloadManager）
我实在想不出来，请大神来co-auther |

建议实现一个测试模仿 MC 客户端安装的密集小文件下载，试试性能，如果你不知道下什么就直接硬编码一个最新版的所有资源文件就好了
另，如果你对 req changes 有什么疑问请提出来，而不是自己闷头写一堆不符合需求的代码，我觉得你对我上个 req 的内容就是没懂或者疑问很多

普普通通的下载器。
因为过于久远，我忘了要求，如果哪里不好提个review。
