uckkk/dsh-html-parse: Structured HTML Parsing

`uckkk/dsh-html-parse` is a Node.js plugin designed specifically for DeepSeek Harness (DSH), aimed at solving the challenges of parsing web page data by agents. Through the `parse_html` tool, this plugin efficiently extracts structured data from HTML files, including titles, Meta information, hierarchical structures, links, tables, and plain text. To install it, use the `dsh plugin add` command and register the plugin in the configuration file. It can be used by calling the tool directly and passing in a file path. Note that installation involves running third-party code, so users should review the source code and confirm environment dependencies before use.
