DeepSeek Harness Right Sidebar File Editor Plugin: dsh-right-editor

The DeepSeek Harness (DSH) right sidebar plugin `dsh-right-editor` provides one-stop file operation capabilities, integrating file browsing and editing. It supports directory browsing, UTF-8 text editing, and image adjustments, and can use Python dependencies to view and edit Word and Excel documents in place. PPT and PDF files support read-only preview only. Installation requires DSH Web to be running and Node.js >= 20; editing Office documents also requires installing the corresponding Python libraries. A hard browser refresh is needed to load the plugin when in use, and file operation permissions are inherited from the current session.
