dsh-search-hub: A Persistent Multi-Channel Search Toolkit for DeepSeek Harness

dsh-search-hub is a plugin for DeepSeek Harness designed to address unstable agent search capabilities. Through persistent configuration and a multi-channel design, it provides Exa semantic search, DuckDuckGo fallback, and xAI Grok integration. Users must manually copy the preset template and restart DSH, then execute searches concurrently using the `multi_search` tool. The plugin supports secure key storage and channel management, but note that network routing depends on the local environment and xAI calls incur costs.
