dsh-live-data: DeepSeek Harness Real-Time Data Plugin

The `dsh-live-data` plugin provides DeepSeek Harness with real-time data querying capabilities through eight keyless APIs, addressing the limitation of models being unable to access real-time information online. It includes 10 tools covering exchange rates, weather, npm/PyPI package versions, GitHub repository information, Bilibili video data, A-share and broad market index quotes, gold prices, and IP geolocation lookup. After installation, users can directly ask for real-time data in a conversation, and the plugin supports setting default parameters to simplify usage. All requests time out within 8–12 seconds. No API key is required, making it suitable for everyday queries and data reference.
