[Ai] feat: 花魁短剧 Next.js 站点初始提交

- 原生 Next.js App Router + 严格 TypeScript 实现花魁短剧 PC/H5 页面，按 src/features/{catalog,content,playback} 组织，保留完整 SEO（metadata、JSON-LD、canonical、robots、llms、sitemap、IndexNow）。
- 主域名通过 SITE_URL=https://huakuidj.com 强制覆盖后端 foreverUrlAddr（config/*.env、src/server/config.ts、src/server/seo/shared.ts、src/server/services/shared.ts），支持邮箱改为 support@huakuidj.com。
- 移除登录与账户体系：删除 /account 全部页面、登录/注册/充值弹窗、收藏点赞、评论、金币解锁及对应 BFF 接口；旧账户地址 GET/HEAD 统一 301 到首页（src/lib/routes.ts REMOVED_ACCOUNT_PATHS），保留游客会话、反馈、图片上传、观看上报与搜索联想。
- 播放页：评论位改为同类推荐 + 热播榜单，锁定集改为 App 观看遮罩与底部弹层，新增简介标签、分集图例与独立视觉皮肤（src/features/playback、src/styles/pages/playback.css）。
- 卡片：短剧/视频卡状态与时长移至信息行胶囊标签，封面角标移至左上角（src/components/catalog/Cards.tsx、src/styles/foundations/base.css）。
- 同步更新单元测试、浏览器冒烟脚本、路由清单与 README。
