dsh-pr-board: DeepSeek Harness Maintainer PR Board

dsh-pr-board is a Kanban board plugin for DeepSeek Harness, designed to address the challenge of managing PR queues in code reviews. It categorizes PRs into five states, including “Waiting for My Action,” “Waiting for Author Action,” and “Ready to Merge,” and provides an Issues board to help maintainers quickly locate tasks that require action. The plugin supports a full-screen board, sidebar counters, and polling reminders, and allows data to be queried via the GitHub CLI, ensuring privacy and security.
