/**
 * 版本更新日志
 *
 * v1.0.7 (2026-02-13)
 * - feat:新增黑名单机制,屏蔽已知非 New API 站点或者 CF 拦截站点
 *
 * v1.0.6 (2026-02-12)
 * - bug:修复签到状态接口返回余额不正确的问题(统一从/api/user/self接口获取余额)
 *
 * v1.0.5 (2026-02-12)
 * - bug:修复签到状态接口获取余额错误的问题
 * - 优化:增加并发数到 15 个,后台请求最多占用 10 个并发(之前是 5 个),提升性能和响应速度
 *
 * v1.0.4 (2026-02-12)
 * - 优化: new api id 获取逻辑,使用 user.id 更可靠
 *
 * v1.0.3 (2026-02-12)
 * - 新增:LDOH 站点白名单机制,只识别 LDOH 卡片中的站点(白名单仅在页面加载时更新一次,避免频繁更新和筛选影响)
 * - 优化:两步验证机制(白名单检查 + New API 特征检测)
 *
 * v1.0.2
 * - 新增:密钥管理功能(创建、删除)
 * - 优化:请求并发控制和优先级
 *
 * v1.0.1
 * - 初始版本:余额查询、签到状态、模型列表
