dsh-token-usage-dashboard: DeepSeek Harness Token Usage Dashboard

DeepSeek Harness (DSH) has launched the `dsh-token-usage-dashboard` plugin, providing developers with real-time Token monitoring. Through a GitHub-style heatmap and metric cards, it aggregates key indicators such as total tokens, daily peak, and active sessions. It supports daily/weekly views, model rankings, and real-time data synchronization. To install it, run `dsh plugin --profile web add github:solstice621/dsh-token-usage-dashboard`. After enabling the plugin, you can view the dashboard in Settings → Stats. Please note potential plugin conflicts, environment dependencies, and data statistics rules.
