灯箱
- 相册页原本已有一套无依赖灯箱（事件委托 + ClientRouter 友好），
  但它写在 gallery/[album].astro 里，只有相册页能用。
  现抽成 src/components/ImageLightbox.astro，挂到 BaseLayout，全站可用。
- 新增 src/plugins/rehype-image-lightbox.mjs：给正文里的 <img> 注入
  data-lightbox-src。跳过链接内的图片（点击应跳转）和显式标记
  data-lightbox-ignore 的图片。
- 顺带让灯箱大图继承原图的 alt 文本（原先固定为空）。
- 正文图片加 cursor: zoom-in 提示。

清理
- 删除 src/plugins/rehype-component-github-card.mjs（165 行）及其在
  rehypeComponents 里的 github 映射：内容里从未使用过 ::github 指令。

验证：构建 41 页通过；文章页正文图片 4/4 带上 data-lightbox-src，
相册页 5 个触发元素不受影响；灯箱脚本按页内联（2.8KB 压缩后）；
正文渲染文本与线上基线一致，无回归。
