备份清单：递归排序对象字段并保留数组顺序

递归按键名整理对象，便于人工检查。backups 的数组顺序不变；排序后的 JSON 文本不能直接当作通用签名规范或所有语言一致的 canonical JSON。

场景与操作说明

备份清单同时记录文件标识、大小、存储类别和分片清单。下面用数据库与资源归档两条记录，练习提取备份文件名、检查字节数和比较校验标记；恢复能力仍需单独验证。

bytes 为示例文件字节数，压缩前后大小应分开记录。

  1. 核对 备份清单 的字段层级，保留 backupId 的字符串类型。
  2. 修改一项输入并运行，观察结果中的值或路径如何变化。
  3. 载入对照样本，复现下面的变化；恢复原例会替换当前输入。

对照样本

对照样本反转 backups 数组。字段排序不会把数组自动排回去，核对输出中的首条 backupId。
