dsh-tool-see-image: Adding Vision Capabilities to DeepSeek Harness

`dsh-tool-see-image` is a plugin tool for DeepSeek Harness that addresses the limitation of pure text models in directly processing images. Acting as an intermediary layer, it invokes a visual model (GLM-4V-Flash by default) to analyze images and return text descriptions. Core features include reading files through the `ctx.fs` sandbox, supporting OpenAI-compatible visual model interfaces, and providing an additional paste-to-text script. Installation requires manually copying the plugin files, declaring dependencies, configuring `cordis.patch.yml`, and setting an API key. Configuration options support customizing the `baseURL`, model, and token limit. Released under the MIT License, it aims to enhance model visual capabilities through lightweight extension.
