llmtrim-stats-plugin: DeepSeek Harness Real-Time Compression Savings Dashboard

`llmtrim-stats-plugin` is an open-source client plugin designed to visualize the data savings from DeepSeek Harness (DSH)'s `llmtrim` compression tool. It provides a dashboard on the Settings page (including KPI cards and a model statistics table), as well as a statistics bar below the input field, supports carousel and static modes, and automatically adapts to the theme. After installation, restart DSH and hard-refresh the browser. The plugin only reads `llmtrim` status and does not modify data, making it suitable for real-time monitoring of token consumption and cost savings in DSH.
