dsh-math-copy：在 DSH Web UI 中复制公式的 LaTeX 源码
dsh-math-copy 是 YizhouLouisLu 维护的 DSH 客户端插件。Web UI 用 KaTeX 渲染公式时，默认复制会得到 glyph 文本而非 TeX；插件监听 copy 事件，从 annotation 取 LaTeX，按配置加行内/块级分隔符写入剪贴板，无公式选区不受影响。安装使用 README 中的 plugin_manager install_bundle，装后重载 Web UI；host 改动需重启 DSH。三项配置可在插件页 math-copy 行修改。已在 dsh core 0.2.0-rc.2 验证。
