Get all ResearchBox links: real hyperlinks from the paper's own url
table, plus a body-text fallback for a BARE mention like "researchbox.org/
801" that the source PDF/HTML never encoded as an actual hyperlink (common
in PDF-converted papers, where a plain-text URL mention loses its link
formatting) — the url table only ever contains links the source
document itself made clickable. Same two-tier approach github_links()
uses for GitHub.
Examples
paper <- demopaper()
rbox_links(paper)
