🚀 Summary of Changes

GitHub’s “Cite this repository” metadata and the README citation blocks still point to the 2025 arXiv preprint and omit Huan Wang and Hanqian Li. Update them to the published JMLR article, with all 12 authors in the official order.

• Update both author lists in CITATION.cff and set the preferred citation to Journal of Machine Learning Research, 2026, volume 27, number 204, pages 1–22, with the official article URL. CFF represents BibTeX number as issue and the page range as start / end.
• Replace the citation blocks in the English, Chinese, French, and Spanish READMEs with the official JMLR BibTeX.

🛠️ Type of Change

• 📝 Documentation update

✅ Checklist

• Performed a self-review.
• Updated the affected citation documentation.
• Preserved existing repository formatting outside the citation blocks.

🧪 Test Plan

• cffconvert --validate -i CITATION.cff passes against CFF 1.2.0.
• Parsed the CFF and compared both 12-author lists (including order), title, journal, year, volume, issue, page range, and article URL against the official JMLR BibTeX; all match (the CFF URL uses HTTPS).
• Confirmed all four README citation blocks exactly match the official BibTeX.
• git diff --check passes. Runtime tests were not run because this change only updates citation metadata and documentation.
