dsh-mattpocock-skills-deck: Visualize and Execute Task Boards in DeepSeek Harness

The DeepSeek Harness (DSH) plugin `dsh-mattpocock-skills-deck` transforms the `mattpocock/skills` repository into a visual task board for managing issues within AI contexts. Users must install it via npm and restart the DSH entry point. Its core features include status-based task lists, a bottom status bar, viewing issue details and comments, handoff to new sessions, quick skill access, and switching between multiple backends (GitHub/local). It integrates task management with AI orchestration. GitLab is not currently supported.
