功能开关：解释 flags 首部插入导致的多处差异

数组按下标逐项比较。在 flags 开头插入记录后，后续元素位置移动，会产生多处修改和一个尾部新增；这不等于多条业务记录都发生了真实字段变更。需要按 ID 配对时应先在自己的业务逻辑中处理。

场景与操作说明

功能开关中，启用标记、灰度比例与定向条件各有语义。查看 JSON 不会更改线上开关，也不证明某个用户已命中规则。

rollout 是示例百分比；本例非负校验没有自动补上 100 的上限。

  1. 核对 功能开关 的字段层级，保留 flagKey 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

对照样本交换 A 与 B。观察新增与删除的方向、修改前后值如何反转；没有差异时交换仍无差异。
