dsh-quartiles: A Quartile Calculation Plugin for the DSH Environment

DSH (DeepSeek Harness) has released an online tool plugin named `dsh-quartiles`, designed to help developers quickly obtain the statistical distribution characteristics of their data during workflows. Maintained by uckkk, it features a pure Node.js implementation, no network dependency at runtime, and a lightweight footprint, and can be invoked directly in DSH sessions after installation. Before use, ensure that the versions of `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` meet the requirements. Since the plugin runs with the permissions of the current process, users are advised to review its source code logic and license (MIT) before deployment.
