dsh-periscope: Enabling DSH Desktop to Support Arbitrary File Drag-and-Drop and Reading

dsh-periscope is a plugin developed specifically for the Windows-based DSH Desktop client, aiming to address the limitation that the official native file upload feature only supports images. By modifying the core `app.asar` file, this plugin enables dragging or pasting uploads for arbitrary file formats, including docx, xlsx, and pdf. After installation, the Agent can read file contents from local paths for processing. However, the plugin requires a Node.js 22+ environment and must be reinstalled after each DSH update, making it an unofficial solution.
