Introducing the DeepSeek Harness Plugin: dsh-diff-vis (Instant File Diff Visualization)

`roushanyyzz/dsh-diff-vis` is a DSH workflow client plugin designed to display file changes directly within a conversation. It supports stacked and side-by-side diff views, inline highlighting, and large-file protection, and can show the precise changes made by `write` and `edit` tools without relying on Git, making it easier for users to track AI-driven file modifications.
