物流轨迹：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。shipments 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

物流标识、重量和轨迹列表分别表达关联、计量和事件顺序。此案例不查询真实物流，轨迹顺序按样本保留。

weightGrams 使用克，不能与千克字段直接按数值比较。

  1. 核对 物流轨迹 的字段层级，保留 shipmentId 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 shipments 数组。字段排序不会把数组自动排回去，核对输出中的首条 shipmentId。
