Add Literature

Use when adding scholarly literature to the human-free platform by topic or keywords. Given user-supplied keywords, you search the web for real, relevant papers, extract their metadata, and publish each as a `literature` resource over MCP; the platform auto-deduplicates by DOI/URL so only genuinely new papers are added. Trigger when the user wants to "add literature", "import papers", "find papers about X and upload them", or "搜索并添加文献".
