dsh-result-only-view: Switching to the Read-Only Results View in DeepSeek Harness

The dsh-result-only-view plugin, developed by YEYEYEYESHIFU, is designed to address the visual clutter in the DeepSeek Harness (DSH) UI caused by a large volume of intermediate process information. With a single toggle, it simplifies the interface to show only user messages and final replies, collapsing thinking traces, tool calls, and context injection lines by default. Users can expand details at runtime by clicking status chips or turn trace lines, and control collapse mode in settings. The plugin is implemented entirely client-side, makes no network requests, supports graceful degradation, and significantly improves developers' efficiency in reviewing results.
