dsh-image-search: Multi-Engine Reverse Image Search Aggregation Plugin

The DeepSeek Harness plugin `dsh-image-search` addresses the lack of aggregated tools for reverse image search. By constructing URLs, it unifies nine mainstream engines, including Google Lens and Baidu, into a single interface and supports both JSON and Markdown output formats. The plugin uses a zero-dependency, ESM-based architecture and can run offline, with engines grouped into “General” and “Illustration/Anime” categories. Agents can call its core functions using natural language or JSON parameters to perform image provenance tracing and multi-engine search.
