DeepSeek Text Attach per superisuer

This extension adds a floating button to the Deepseek interface that lets you insert the contents of a local file directly into the prompt area. Instead of uploading files to a server, it reads the file locally and injects the content as plain text into the prompt. This makes the process of sharing code, logs, or other text data much faster and more efficient. It supports all file types and works entirely on the client side for privacy and speed.
