dsh-balance-view: DeepSeek Harness Real-Time Balance Monitoring Dashboard

`dsh-balance-view` is a balance-monitoring plugin for DeepSeek Harness, designed to display API key account consumption at a glance via a persistent panel. The plugin supports balance queries, real-time refresh (on mount, turn end, 5-minute polling, and manual refresh), and the `/balance` command. It must be installed via the CLI and takes effect after a restart. The plugin uses a “command text output + panel local state” pattern to avoid data pollution caused by writing to session logs. It is suitable for users who need precise control over API consumption, and the installation source must be trusted.
