dsh-minimax-usage: Display MiniMax Token Plan Subscription Usage in the Web UI

dsh-minimax-usage is a client plugin for DeepSeek Harness (DSH) designed to display the remaining quota of a MiniMax Token Plan next to the model selector in the Web UI. By reading the official API, the plugin provides an inline progress bar, hover details, and click-to-refresh functionality, supports display by Provider, and includes a smart automatic refresh mechanism. Install it using the command `npx @deepseek-ai/dsh plugin --profile web add dsh-minimax-usage`. Note that subscription Keys and regular API Keys must be distinguished, and configuring pnpm to allow build scripts may be required during installation.
