dsh-premium-budget: Premium Budget Plugin

`dsh-premium-budget` is a plugin for DeepSeek Harness (DSH) designed to address the lack of rigorous logic in LLMs when handling household insurance planning. Maintained by developer uckkk, the plugin is written in pure Node.js, does not rely on external network interfaces, and supports direct execution locally or within the DSH environment. Before installation, the dependencies `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` must be satisfied. After installation, the `premium_budget` tool can be invoked directly in conversations to generate plans. The plugin is released under the MIT license and is suitable for scenarios requiring stable, localized computing capabilities.
