zotero-mcp-dsh: Connect local Zotero library to DSH

When writing academic papers, asking the model to help organize the main text is not difficult, but citing is challenging: the model does not know what literature exists in your library, and the DOIs and years provided casually are often fabricated. Existing approaches either involve manually organizing `.bib` files or pasting literature metadata piece by piece into the context, both of which interrupt the workflow. The `zotero-mcp-dsh` introduced below is a DSH plugin maintained by LiJunfeng000000000000, currently at version 0.1.0 and released under the MIT license. It connects a local Zotero library to DSH, enabling the model to retrieve literature, read basic information and full PDFs, and export BibTeX directly within the session, facilitating the construction of LaTeX reference libraries and the insertion of LaTeX citation commands.
