dsh-diamond-care: Diamond Care

The DeepSeek Harness plugin `dsh-diamond-care` is a fun style-customization tool implemented entirely in Node.js, designed to generate watch and jewelry care plans for lifestyle service scenarios. It makes no network requests, and all logic runs locally. Users can install it via a command and invoke the `diamond_care` tool to obtain professional care recommendations. The project is licensed under the MIT License and requires specific versions of DeepSeek ecosystem libraries to run.
