Playwright 1.64.1 没有 page.accessibility（Puppeteer 的 API）， broker 的 snapshot 调它必走异常分支。改调 Page.aria_snapshot() （字符串）；guard 的 truncate_a11y 换成字符串版 truncate_aria （179a86d 原样），detect_injection/detect_form_risk 加字符串 分支（dict 分支保留）；两边 fake 与 P4 文档同步改。a11y-only 契约不变：不读原始 DOM、不走 JS eval。 测试：test_chv_muse_p2 + test_chv_muse_p4 114 OK；全量 2523 OK （skipped=10）。
