dsh-simplify: DeepSeek Harness UI Cleanup and Customization Tool

dsh-simplify is a UI simplification plugin for DeepSeek Harness, maintained by Anna-la. Its core feature is to remove redundant page elements via right-click after entering Clean mode and persist these removal records to the file system, addressing the issue of browser `localStorage` becoming unavailable after restarts. The plugin retains configurations across restarts and uses `MutationObserver` to monitor page changes in real time, preventing removed elements from unexpectedly reappearing. Users can view the list of removed elements and an interactive preview, and restore elements under “Settings → Simplify.”
