feat(papers): 论文内置阅读——arXiv iframe 零再分发合规方案

Agensh（arXiv 2609.26781）在线研读页：/papers/agensh/ 双轨薄壳
_PaperView 共享视图+六词条；信息条含标题/作者/abs 链接/授权声明
（arXiv nonexclusive-distrib 1.0，非本站托管）/下载钮。

合规红线：许可证禁第三方再分发→仓内零 PDF 副本，iframe 直嵌
arxiv（实测无 X-Frame-Options）；微信 webview 前置 UA 检测加
is-wechat 类、iframe 不挂 src 零无用请求、兜底卡指引右上角浏览
器打开；非微信 data-src 懒挂载+9s 弱兜底+noscript 兜底。正文
入口卡双轨已渲染。

车道：op-gitea（专项四断言+E2E 34/34）；收编复验六断言全过
（iframe/授权/微信降级/en/入口卡/零 PDF）

验证: E2E 34/34；微信 UA 模拟 is-wechat=true src 空 提示在；
      git status 零 .pdf

Spec: none (论文阅读页，车道级交付)
