dsh-dseyes: Providing native image upload experience for DeepSeek Harness text-only models

dsh-dseyes is an MIT-licensed plugin for DeepSeek Harness (DSH) designed to address the limitation where pure text models cannot directly process images. This plugin enables users to paste or drag images into the Web GUI, displaying them as attachments while preserving the original images. Prior to sending the request to DeepSeek, the host automatically invokes the Zhipu GLM free vision model (e.g., glm-4v-flash) to identify image content, generate a textual description, and replace the original image block, allowing the text model to formulate its response based on that description. The plugin supports an automatic fallback chain, result reuse, and diagnostic interfaces; the conversation continues uninterrupted even if image reading fails. Installation requires Node >= 22, configuration of GLM_API_KEY or ZHIPU_API_KEY, and running `dsh plugin --profi...`
