/**
 * Surge 脚本：捕获 peoplehub 响应中的 gamertag
 *
 * 功能：
 *   - 保持原有：维护最新 gamertag 到 $persistentStore.gamertag
 *   - 新增：把每次捕获追加到 gamertag_records 数组（相邻相同值去重）
 *
 * gamertag_records 结构：[{gamertag, ts}, ...]
 *   - 匹配由网页脚本动态完成，本脚本不做任何配对
 *
 * Surge 配置：
 * [Script]
 * capture_gamertag = type=http-response, pattern=^https:\/\/peoplehub-public\.xboxlive\.com\/people\/gt\(.+\), requires-body=true, script-path=xxx.js
 *
 * [MITM]
 * hostname = %APPEND% peoplehub-public.xboxlive.com
