dsh-paperlens: Literature Search Research Copilot Plugin

`dsh-paperlens` is a Cordis plugin in the DeepSeek Harness (DSH) ecosystem for scientific research. Built on the “everything is a plugin” principle, it runs entirely locally to ensure data privacy. It offers core capabilities including multi-source retrieval, citation formatting, reference database management (SQLite), and batch export in RIS/BibTeX. It supports searches via OpenAlex and CrossRef, provides multiple citation styles such as APA and GB/T 7714, and supports scoring and tag management for paper metadata. The plugin can be installed with a command without manual configuration and does not require browser authentication, making it well suited for efficient literature retrieval, citation generation, and local archiving within the DSH environment.
