xiaoyanjin15-ux/dsh-history-mirror-plugin: DeepSeek Harness Right-Side History Mirror Panel

`dsh-history-mirror-plugin` is an open-source plugin for DeepSeek Harness Web, designed to address the difficulty of scrolling and locating content in lengthy conversations. The plugin adds a “History” button to the conversation title bar, mirrors the current conversation content into an independent panel on the right, and enables separate scrolling, real-time synchronization, and reuse of code styling. It follows a security-focused design, avoids accessing sensitive data, and uses a sandboxed iframe to handle web preview. The plugin takes over the `details` single slot to provide convenient context viewing within the browser page. To install it, run the specified `npx` command, then refresh the browser to enable it.
