 * ============================================================
 *  豆瓣下载助手 v5.4.1   （原名「豆瓣电影下载大师」）
 *  更新日志:
 *    v5.4.1 - 结果条目级核验，误报清零（本版核心）
 *    【问题】旧版把「站点能打开」当成「该站有这部片」：
 *             - 96/160 站点标记为「仅可达性判定」，只要返回 200 且页面 >500 字节即标绿
 *             - 其余走整页文本打分，而搜索页必然回显查询词（<title>、搜索框 value、
 *               面包屑、甚至「没有找到 X」这句话本身），标题命中即 +4，零结果页也能过阈值
 *             - 实测：用一部根本不存在的影片检索 160 站，旧逻辑误报 150 站（94%）
 *    【重做】新增结果条目校验器 verifyResults()，只认「结果行」：
 *             - DOMParser 解析响应，锚点文本或 href 命中片名
 *             - 命中若只出现在搜索型链接（?s=X、/search/X、?wd=X）中 → 判为回显，丢弃
 *             - 该行必须另带资源证据：磁力/网盘直链、发布标记(1080p/WEB-DL/x264/中字)、
 *               四位年份、或详情链接；仅「片名+Download」这类模板回显不计分
 *             - 行内出现「没有找到/暂无相关/no results」→ 整行否决
 *             - 所有站点统一走此校验，删除 detect 开关（不再有「仅可达性」这一档）
 *    【站点集】按新标准重扫 1360 个可达域名 + 374 个历史端点，只保留能真正出结果的：
 *             下载 9 · 网盘 6 · 在线 28 = 共 43 站，全部逐站复测
 *             （不存在的片名在最终站点集上误报 0）
 *    【吸纳参考脚本 4.1.1 的优点】
 *             - 逐条结果解析（DOMParser + 真实条目计数）替代整页关键词打分 —— 本版核心
 *             - IMDb 评分三级回退解析：__NEXT_DATA__ → application/ld+json → 正则
 *             - 「站点答了但无结果」不再写 24h 健康度黑名单（旧版一部冷门票会把站点拉黑
 *               一整天，换部片子也被误判跳过）；仅传输层失败才缓存不可用
 *             - HTTP 404 视为站点的有效应答（进入结果校验）而非站点故障
 *    【未采纳】withCredentials（公开搜索页无需 Cookie，且会触发带凭据 CORS 失败）、
 *             防机器人「去验证→回来重试」引导与结果条目列表（均需新增界面元素，
 *             与「不改 UI」冲突）；网盘站自有 JSON 接口实测仅 2/62 可用，不成规模。
 *    【界面】面板 DOM 结构、类名、层级与 v5.3.1 完全一致，未增删任何元素。
 *
 *    v5.31 - 站点扩容（三类各新增实测可用站，按实测延迟分层）
 *    【采集】新增候选 2,292 个域名：FMHY 国际清单（video/torrenting/downloading 三页）
 *             + 14 篇中文影视/网盘/磁力推荐榜单，全部来自可抓取来源，不凭记忆编造网址
 *    【验证】可达性初筛 → 首页指纹（maccms/WordPress/Next/表单 action）→ 定向搜索端点
 *             → 真实片名请求 + 结果页特征判定，两轮（严格 / 前端渲染宽松）互补
 *    【相关性】结果页须含发布标记(1080p/BluRay/x264/磁力)或影视/网盘字样，
 *             并剔除过期域名被抢注后的跳转站（丹麦高校、工具箱、Object Cache 等 8 例）
 *    【新增】下载 +27 · 网盘 +22 · 在线 +30 = 共 79 站，
 *             每类内部按实测延迟三分位划 快速/中速/慢速；站点总数 81 → 160
 *    【说明】在线类目标 30 已达成；下载 27、网盘 22 为「实测可出结果」的上限——
 *             中文网盘搜索生态可枚举站点已基本收齐，其余候选已停放/失效/需代理
 *
 *    v5.3.0 - 更名·站点实测重排·代码精简
 *    【更名】程序名统一为「豆瓣下载助手」：脚本名、面板标题、启动标记、日志前缀
 *    【站点校准】246 站全量实测（真实关键词请求 ×3 轮重试 + 根域二次探测 + 响应体特征判定）：
 *             - 删除 165 个连不上的站点：域名解析失败 29、连接超时 51、拒绝连接 8、
 *               HTTP 4xx/5xx 40、Cloudflare 挑战页 8，以及返回「域名出售/跳转/人机验证」
 *               空壳却仍被标绿的站点（人人影视·深影字幕组·MK影视·YaPan·云盘精灵 等）
 *             - 修复 9 个「站点存活但搜索路径写错」的网盘站端点（搜百度盘·影猫导航·夸克资源·
 *               天天云搜·海搜·知了搜·盘友圈·盘库吧·盘搜搜·云盘4K，原 /search?keyword= 全为 404）
 *             - 新增 6 个实测可用站：蓝光电影(下载)·盘搜Pro·天天搜索·皮卡搜索·夸父资源社(网盘)·
 *               影猫仓库(在线)·东京图书馆(国际BT)
 *             - 国际站按类收敛：下载 38→7、在线 46→17，仅保留实测可达者
 *             - 结果：246 → 81 站，全部复测可达；快速层实测可用 12 → 43
 *               （下载快速 0→4、在线快速 0→10、网盘快速 12→29）
 *             - 梯队按实测延迟重排：快 <1s · 中 1-3s · 慢=国际站(需代理)；
 *               原快速层中已连不上的站点全部剔除而非降级
 *    【代码精简】界面元素与 DOM 结构逐节点校验为完全一致：
 *             - 移除 GBK 码表模块（仅服务于已失效的 4 个 GBK-POST 站点）与 POST 检测分支
 *             - 梯队可见性由「每个站点完成后全量重扫」改为增量计数，消除 O(n²) 扫描
 *             - 删除未被消费的字段（导演/主演/片长/类型、noResult、badgeEl、useImdb）、
 *               站点专用解析器表（10 项对应站点已全部下线）、旧版 GM.xmlHttpRequest 兼容分支
 *             - 合并三段同构的分区初始化、面板卸载与缓存清理逻辑；定时器 5 路收敛为 1 路轮询
 *             - 修正 v5.2.1 遗留并发缺陷：pool 的 done 回调在同帧多站点收尾时会重复触发，
 *               导致下一梯队被并发重复启动、可用站点计数翻倍（如显示 133/87）
 *             - 体积 1927 行/114KB → 1578 行/89KB（-22%）
 *    v5.2.1 - 界面精简（删除「复制全部可用链接」按钮）
 *    v5.2.0 - 纯白实底化·结果纯化·国际站全自动
 *    v5.1.0 - 配色可读性重构·去荧光·全量淡字强化
 *    v5.0.0 - 视觉降噪重构·信息提纯·双模适配
 *    v4.x   - 分层加载 / FMHY 国际站集成 / 加权评分 / iOS 毛玻璃
 *    注：CSS 类名与存储键沿用 ddm- 前缀（内部标识，不显示于界面）。
