dsh-delhi-city: Returns Delhi City Information

The DeepSeek Harness (DSH) plugin provides query capabilities for Delhi city information. It is maintained by uckkk, open-sourced under the MIT License, and implemented purely in Node.js with no network dependencies. Before installation, ensure the environment includes `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6). After installing it by running `dsh plugin add github:uckkk/dsh-delhi-city`, you can invoke the relevant tools in a conversation to retrieve basic information about Delhi.
