dsh-brand-identity: Brand Design System Reference

DeepSeek Harness (DSH) provides a localized brand design reference tool, maintained by uckkk. This plugin is implemented purely in Node and has no network dependencies, making it suitable for privacy-sensitive or offline environments. Installation requires adding it via the command line and configuring `package.json`. Once enabled, it can directly call local tools to obtain brand design references. Please review the source code yourself before use to ensure security.
