dsh-html-to-text: Local HTML to Plain Text

The DeepSeek Harness plugin `dsh-html-to-text` provides a fully local HTML-to-text solution. Its core features include a pure Node.js implementation, no network requests, and no external dependencies. Installation is performed by adding it via the command line and configuring it in `package.json`; once enabled, the tool can be invoked during a session. It is well suited for agent development scenarios with privacy or network constraints, and it is recommended to review the source code before installation.
