Manage the user's Zotero library — search papers, add/organize items, export citations, OCR PDFs, and run semantic search (RAG). Use whenever the user mentions Zotero, "我的文献库", finding/adding/citing papers, "参考文献", "文献综述", or wants to read/extract content from their PDFs. Requires Zotero desktop running with the zotron XPI plugin. Check with `zotron ping`.

Set up Zotron — verify `zotron ping` works; if missing, download the release XPI to Downloads and guide Zotero's native install dialog. Use when the user asks to install, configure, bootstrap, or verify Zotron.
