dsh-latexcp: DSH Web Interface LaTeX Formula Copy Plugin

dsh-latexcp is a LaTeX formula copy plugin for the DeepSeek Harness (DSH) web interface, designed to resolve the layout fragmentation issue caused by directly selecting formulas. It allows users to copy the TeX source code of any formula to the clipboard with a single click via a floating button when hovering over it. The plugin supports switching the default format between dollar signs ($...$) and slash parentheses (\(...\)), and automatically identifies inline or display formulas to output the correct single or double delimiters. Built with a pure browser-side architecture and no backend services, it ensures high security and privacy by reading formula source code from the current page's DOM memory and triggering copy only upon user interaction. It can be added to the DSH web profile via the GitHub repository during installation without requiring additional configuration.
