dsh-guangzhou-city: A Network-Independent Guangzhou City Information Query Plugin

The DeepSeek Harness plugin `dsh-guangzhou-city` is designed to address the pain point of relying on external APIs during DSH development. Built with pure Node.js, it can run locally without internet access and focuses on retrieving Guangzhou-related information. Developers can easily install it and invoke it directly in conversations, making it suitable for intranet or network-restricted environments. Before use, the source code’s security and license should be checked.
