auto-vision: DSH All-in-One Image Plugin

`auto-vision` is a DSH plugin designed to resolve errors or rendering issues caused by directly pasted images. It automatically cleans image data and registers the `see_image` tool, allowing text models to invoke vision models to read content automatically without modifying the original logic. The plugin supports free vision models from Zhipu and ModelScope, and is also compatible with any OpenAI-compatible platform. During installation, the plugin directory must be copied into `node_modules`, and its configuration must be added to `cordis.patch.yml`. Users can configure the API token via environment variables or a credentials file. By default, it uses ModelScope, but it can be switched to Zhipu or a local model. The DSH process must be restarted before use.
