Subject: [PATCH] feat: expand smart import to support additional citation
 formats
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds detection and parsing support for more input formats that
citation.js can handle, making the smart import feature more powerful.

New supported formats:
- RIS format (common export from EndNote, RefWorks, Zotero)
- PubMed Central IDs (PMCID) in addition to existing PMID support
- Wikidata IDs (e.g., Q12345 or wikidata:Q12345)
- Zenodo records (URLs and IDs like zenodo.1234567)
- Citation File Format (CFF) for software citations

Benefits:
- Users can now paste RIS exports from reference managers directly
- Support for Wikidata citations enables citing entities/concepts
- Zenodo support facilitates citing datasets and research outputs
- CFF support enables proper software citation
- Enhanced format detection provides better user feedback

The smart parser now detects all these formats automatically and
displays the appropriate format hint to users. All formats are
processed through citation.js's robust parsing engine.
