xby-plant-recognition: Plant Recognition Plugin

DeepSeek Harness (DSH) provides the `xby-plant-recognition` plugin for recognizing plant information in conversations. The plugin supports identifying details such as plant name, family, genus, and species, and offers four core functions: `set_xby_apikey`, `plant_recognition`, `plant_recognition_for_data_base64`, and `plant_recognition_for_data_file`, corresponding to setting the API key, recognizing an image URL, BASE64-encoded data, and a local file path, respectively. The installation command is `dsh plugin --profile web add github:xby_skill/xby-plant-`.
