feat(i18n): GLM 直译 10 篇书评——英文站全量覆盖，全部 locked 防回退

TMT 月度免费额度耗尽，改由 GLM 模型直译（质量高于机翻）：面纱/佩德罗·巴拉莫/
海风中失落的血色馈赠/等待戈多（源更新重译，修正旧版人名漂移）/你谈/述罪
+ 四篇排版测试稿。翻译纪律：frontmatter 除 title 外字节级保留 + locked: true；
markdown 与排版包装器原样保留只译内文；文学书名用原著通行英文题名
（The Painted Veil / Pedro Páramo / Waiting for Godot / The Lost Salt Gift of Blood）。
同步刷新 translation-state 的源 sha256（locked + 幂等双保险）。
仪表盘英文覆盖 10→15；E2E 筛选断言随新照片动态对齐（65/65）。

验证: pnpm astro build exit 0（54+ 页，EN 目录 14 篇全生成）；content-lint 0/0/0；E2E 65/65；gen-admin-stats 英文=15

+This post is a three-media pipeline specimen: it verifies how a markdown image and HTML5 video/audio are handled along the build chain, for use in visual-regression and multi-device testing (marked hidden — do not list).
+
+## Image (markdown syntax, optimized by sharp at build time)
+
+![Sample photo](../posts/assets/media-sample/sample-photo.jpg)
+
+<p class="fig-cap">The new caption syntax: the fig-cap class — a copy of a specimen shot from the photos directory (1600×2400 portrait).</p>
+
+## Video (raw HTML, H.264 320×240, generated with ffmpeg testsrc2)
+
+<!-- Video/audio use absolute public/media/ paths: relative references in raw HTML bypass the
+     bundler (this once caused a verified 404), in line with the writing guide's rule that
+     "large videos live in an out-of-repo store under the /media/ namespace" -->
+
+<video controls preload="metadata" width="320" height="240" src="/media/media-sample/sample-video.mp4"></video>
+
+*Native `<video>` control, no JS; source file 45KB, faststart enabled.*
+
+## Audio (raw HTML, 440 Hz sine-wave mp3)
+
+<audio controls preload="metadata" src="/media/media-sample/sample-audio.mp3"></audio>
+
+*Native `<audio>` control; source file 18KB.*
