dsh-hanfu-buy: A Hanfu Shopping Pitfall-Avoidance Plugin

DeepSeek Harness (DSH) now includes a new Hanfu shopping assistance plugin, `dsh-hanfu-buy`. Maintained by user `uckkk` and licensed under MIT, it is implemented in pure Node.js with no network dependencies. After developers install it with the command `dsh plugin add github:uckkk/dsh-hanfu-buy`, they can invoke the `hanfu_buy` tool in a session to obtain outfit suggestions, making it suitable for scenarios that require integrating Hanfu recommendation capabilities into an agent.
