DeepSeek Harness Plugin: xby-detect-vehicle (Vehicle Detection)

`xby-detect-vehicle` is an inference plugin for vehicle detection in the DeepSeek Harness (DSH) ecosystem. It relies on an external API to recognize vehicle types, including license plates, and their detection boxes. The plugin provides persistent storage for API keys and supports three detection methods: image URLs, Base64-encoded data, and local file paths. After installation, you need to register on the official website to obtain an API key and can then perform vehicle detection by calling the corresponding function.
