dsh-balance-status: DeepSeek Balance & Usage Monitoring Plugin

`dsh-balance-status` is a lightweight plugin for DeepSeek Harness (DSH) that displays account balance and usage directly in the bottom status bar of the web interface. It requires no browser permissions and supports one-click details, forced refresh, and automatic updates. Installation can be done via local packaging or a GitHub repository, after which balance monitoring is enabled once configured. The plugin uses a balance-difference accounting method for safe and reliable operation, but some data will be lost after restarting the process, and it is not applicable to the image generation feature.
