dsh-design-patterns: UI Design Pattern Reference

`dsh-design-patterns` is a local UI design pattern reference plugin maintained by uckkk. It is implemented in pure Node.js and does not rely on network requests, aiming to provide instant design pattern lookup capabilities for agent development. Users can install it via a command and enable it in a configuration file. To use it, directly invoke the plugin tool to retrieve reference information. Installing the plugin runs third-party code, so it is recommended to review the source code and license before installation to ensure security and compliance.
