frank-nf/dsh-drop-md: Drag-and-Drop Markdown Enhancer for DeepSeek Harness

frank-nf/dsh-drop-md is a plugin for the DeepSeek Harness (DSH) client, designed to address the inefficiency of integrating file content. It provides three core features: inlining the content of small Markdown files, referencing large files using `@` to save tokens, and installing SKILL.md with one click. Users can quickly integrate documents or skills simply by dragging and dropping, greatly simplifying file management in DSH.
