// 铸渊专线 · Clash Verge 订阅增强脚本 v2（广州中转更新稿）
// v1 功能保留：注入冰朔的两个新加坡 VLESS+Reality 专线节点 + 智能接管组
// v2 新增（2026-08-23）：
// - 注入广州中转节点「铸渊-大脑-粤快」(43.139.217.141:8444)、「铸渊-面孔-粤快」(43.139.217.141:8443)
//   中转链路：广州 BS-GZ-006 realm → 新加坡落地，实测握手 ~350ms、零丢包
// - 新增 🛡️ 粤港快线（url-test）：两个中转节点自动择优
// - 🛡️ 专线接管 成员调整为：粤港快线(中转优先) → ♻️自动选择 → SG 直连兜底
// - 🚀节点选择 最前面插入 🛡️ 粤港快线
// 节点参数：中转节点的 uuid/pbk/sid 跟随各自新加坡落地节点，与中转端口无关
// 全程幂等：重复执行不重复添加、不改变已收敛结构
