dsh-class-budget: Interest Class Budget Calculation

DeepSeek Harness (DSH) has introduced a plugin-based architecture to enhance agent capabilities. This article introduces the **dsh-class-budget** plugin, maintained by user uckkk, for calculating and planning extracurricular class budgets. The plugin is implemented purely in Node.js, has no network dependency, and supports precise, parameter-based budget calculations while returning recommendations. Users can install it via a command and invoke it directly within a DSH session, providing concrete budget calculation capabilities to the DSH ecosystem.
