dsh-ppt-studio: Converting Markdown to HTML Slides and PPTX

`dsh-ppt-studio` is a plugin for DeepSeek Harness (DSH) that automatically converts Markdown or attachments into presentations. It supports generating HTML slides, editable PPTX files, and JSON manifests, provides multiple built-in themes, and allows local master files to be used as templates. Users must install Node.js 22+ and use tools such as `ppt_create` to generate files. Note that this plugin conflicts with existing plugins of the same name and does not support features such as Slidev or chart generation.
