a2ui-render-in-dsh: Rendering Interactive A2UI Cards in DSH Conversations

`a2ui-render-in-dsh` is a DeepSeek Harness (DSH) plugin maintained by baihui-ai, designed to render interactive UI cards in conversational flows via the A2UI protocol, addressing the limitations of pure text interaction when handling complex data and forms. It supports rendering 15+ components, including quizzes, forms, charts, and flowcharts, and features streaming progressive rendering, in-place updates, zero external dependencies, offline operation, and submission in natural language. After installation, it must be integrated into DSH builds; the agent retrieves rules via `a2ui_catalog`, uses `a2ui_render` to generate cards, and translates user actions into natural language feedback, creating a complete closed-loop interaction.
