elviass/dsh-cost-insights: DeepSeek Harness Local Usage and Cost Analysis Plugin

`elviass/dsh-cost-insights` is a local usage and cost analysis plugin specifically developed for the DeepSeek Harness (DSH) web interface. It aims to address the issue of users lacking a unified entry point to review Token consumption, cache hit rates, API balances, and model prices. Distributed under the MIT license as an unofficial extension, it is compatible with DSH versions `>=0.1.0-rc.7 <0.2.0` and Node.js environments `^22.19.0 || >=24.0.0`. It also supports automatic adaptation to language and theme settings. Core features include multi-dimensional statistics (by conversation, workspace, model, etc.), visual chart analysis (line charts, heatmaps), real-time price and exchange rate synchronization (USD/CNY conversion), and API balance display.
