dsh-jina: Integrating jina-cli's 12 API tools into DeepSeek Harness

# Introduction DSH's built-in `web_search` covers general web retrieval; however, to obtain arXiv official direct links, SSRN paper originals, or perform web screenshots, text vectorization, and document reordering, one typically needs to write glue code at the host level and register the tools manually. dsh-jina eliminates this step: it encapsulates the Jina AI API capabilities (behind `jina-cli`) into 12 `jina_*` model tools within DSH and provides an API key configuration card with real-time balance checking on the Web settings page. Below, we introduce its features, installation methods, and selection considerations. # What is dsh-jina dsh-jina is maintained by minatoAI, licensed under MIT, and is currently at version 0.5.2.
