DeepSeek Harness Plugin: dsh-ark-balance

dsh-ark-balance is a widget-style plugin designed to address the pain point of checking the free resource package balance of the Volcano Ark Collaboration Reward Program in a Web interface. It reuses the official CLI data source, requires no additional login, and supports drag-and-drop layout, multi-dimensional filtering and sorting, and overlay metric display. The plugin features smart low-balance alerts, auto-refresh, and graceful degradation, ensuring guided onboarding when the CLI is not installed. It is a pure Node.js ESM module with zero dependencies and easy installation.
