DeepSeek Harness Plugin dsh-subagent-vision: Enabling Pure-Text Main Agents to Read Images Directly in Conversations

The DeepSeek Harness plugin `dsh-subagent-vision` addresses the inability of pure-text models to handle images. It delegates image processing tasks to a configured vision subagent, enabling the main agent to remain text-only while receiving visual results. The plugin supports pasting, dragging and dropping, and importing images via file path; provides a native Web GUI experience; and enforces a 25 MB image size limit. After installation, users only need to describe the task to the agent, and the plugin automatically invokes the subagent's `read_image` tool to complete it.
