attach-plus Plugin: DSH Input Box “/” Command and Categorized Upload

The Web UI plugin for DeepSeek Harness (DSH) modifies the layout to separate the command menu (/) from the file upload (+) button. Users can click the newly added circular button to open the browser and select an image or document. The plugin supports uploading images in formats such as PNG, JPEG, and GIF, and supports saving documents to disk. Images are processed through the native pipeline, while documents are uploaded via API and their paths are recorded in the draft, allowing the model to read local attachments. Installation requires using the specified command and restarting DSH.
