dsh-espresso: Espresso Extraction

The DeepSeek Harness (DSH) plugin dsh-espresso is a pure Node.js tool focused on espresso extraction. It can generate a structured extraction protocol offline based on parameters including coffee dose and water temperature. The plugin aims to reduce reliance on LLM inference and improve output determinism, making it suitable for agent development that requires professional coffee guidance. The installation command is `dsh plugin add github:uckkk/dsh-espresso`. Because it runs with the current process permissions, it is recommended to review the source code before use to ensure security and compliance.
