DeepSeek Harness Plugin: dsh-prime-factors Prime Factorization

The DSH plugin `dsh-prime-factors`, maintained by user uckkk, provides local prime factorization capabilities for DeepSeek Harness. It uses a pure Node.js implementation without any network requests, ensuring stable and secure computation. Installation requires the corresponding versions of `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`, and the plugin can be installed with the `dsh plugin add` command. After installation, it can be used by invoking the tool directly, making it suitable for scenarios that require high computational stability and have no internet access.
