PR Review: fix: standardize BibTeX citation to match main repo

This is a clean, documentation-only change. Here is my feedback:

Summary

The change syncs the BibTeX citation with the canonical upstream version. The diff is minimal and well-scoped.

Positive Observations

• Cleaner citation key: saraiva_2025_rxivmaker is much more readable than saraiva2025rxivmakerautomatedtemplateengine and follows a common BibTeX convention (author_year_shortid).
• LaTeX encoding for special characters: Switching from a raw UTF-8 character to the LaTeX-escaped form is a good improvement for BibTeX compatibility — raw UTF-8 can cause parsing errors in some BibTeX processors.
• Reduced indentation: Moving from 6-space to 2-space indentation improves readability of the BibTeX block.

Minor Observations

1. Title capitalization and missing braces: The title uses sentence case, which matches the arXiv canonical entry. However, neither version protects the product name with braces (e.g., {Rxiv-Maker}). In some bibliography styles, BibTeX may lowercase the entire title, potentially turning Rxiv-Maker into rxiv-maker. Since syncing with the canonical citation is the stated goal, this is acceptable as-is — but worth noting for users who copy this citation into their own work.

2. Removed primaryClass: Removing primaryClass={cs.DL} is fine since it is optional. It is a useful field for arXiv preprints as it tells readers the subject category at a glance, but removing it to match the canonical version is reasonable.

3. Test plan checkbox: The test plan item is unchecked. Since this is a Markdown code block it will render correctly regardless, but worth ticking off before merging.

Verdict

Approved with minor notes. This is a low-risk, well-motivated documentation fix. The main item to be aware of is the missing brace protection around Rxiv-Maker in the title field, but since this mirrors the canonical upstream citation it is not a blocker here.
