dsh-github-live: Fetch GitHub Repository Info in Real Time

dsh-github-live is a DeepSeek Harness (DSH) plugin maintained by uckkk, aimed at resolving the inefficiency and error-proneness of agents retrieving GitHub repository status by providing a real-time online fetching capability. Implemented purely in Node.js, it supports querying repository information. The installation command is `dsh plugin add github:uckkk/dsh-github-live`; before use, ensure the environment satisfies the dependencies on `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools`.
