dsh-math-suite: A DSH plugin package that installs math, wolfram, and diffgeom at once

`dsh-math-suite` is a DeepSeek Harness (DSH) plugin aggregation package maintained by hatter123 and licensed under the MIT License. It is designed to address the cumbersome multi-backend installation and configuration process in mathematical calculation scenarios by enabling three distinct math tool plugins simultaneously through a single installation. The suite includes the following three core tools: 1. **`math`**: Powered by mathjs, it supports numerical evaluation, simplification, and symbolic differentiation. It has no prerequisites, is implemented in pure JavaScript, and is always available. 2. **`wolfram`**: Powered by Wolfram Mathematica, it supports complex calculations such as integration, equation solving, and limits. It requires an external environment providing the Wolfram Engine or wolframscript. 3. **
