dsh-latex-tools: Copying LaTeX and Exporting SVG in DeepSeek Harness Web UI

dsh-latex-tools is a MIT-licensed plugin for the DeepSeek Harness (DSH) Web UI, designed to address users' specific needs when viewing mathematical formulas within the interface. It allows users to hover over any inline or block-level LaTeX formula and quickly copy the TeX source code to the clipboard, or render it via MathJax and export it as a self-contained standalone SVG file—suitable for use in papers, presentations, and similar scenarios. Its core features include full offline functionality (no CDN required), support for display mode export, and automatic loading with the Web UI after installation. Installation requires starting the Web UI first, then adding the plugin via `npx @deepseek-ai/dsh plugin --profile web add dsh-lat`.
