/*
 * PingMe CK 抓取 - Quantumult X Rewrite
 *
 * 订阅地址：
 * https://gitea.chickliu.fun/Hermes/qx/raw/branch/main/conf/pingme.conf
 *
 * 功能：
 * - 监听 api.pingmeapp.net/app/queryBalanceAndBonus、checkIn、videoBonus
 * - 抓取 pingme_multi.js 需要的 url / paramsRaw / headers
 * - 弹窗输出可直接追加到 NiuPanel /app/data/scripts/pingme_ck.json 的 JSON 对象
 *
 * 安全：不上传 CK，不请求第三方；仅在 QX 本地保存最近一次抓取结果。
