/**
* Xbox Cart History Switcher
*
* 功能：
* 1. 访问 https://carthistory.com/ → 按时间戳最近邻匹配 cart 和 gamertag，展示卡片
* 2. 点击切换 → 覆盖 $persistentStore 中的 cartId / authorization / gamertag
*
* 匹配策略（核心）：
* - 读取 cart_records 和 gamertag_records 两个数组
* - 对每条 cart，在 gamertag_records 中找时间戳绝对差最小的一条
* - 若最小差值超过 MATCH_WINDOW_MS，则该 cart 的 gamertag 显示为 "(未知)"
* - 不在存储里记录"已匹配的三元组"，每次页面刷新都重新计算
