dsh-slides: Generating Self-Contained HTML Slides for DeepSeek Harness Agent

`dsh-slides` is a plugin for DeepSeek Harness (DSH) designed to address the need for agents to directly generate presentation slides. Through the `make_slides` tool, it converts structured data into self-contained HTML slides, supporting offline presentations, printing to PDF, and exporting to PPTX. The plugin provides five preset themes with no manual style configuration required and supports multiple layout types. Agents can generate presentations using natural language instructions and can specify the output format. This plugin is released under the MIT license.
