Show both maintainers in pkgdown sidebar

[carmen-cabrera]

Summary

• keep DESCRIPTION valid with a single cre package maintainer, as required by R package metadata rules
• customize the pkgdown homepage Developers sidebar so Francisco Rowe and Carmen Cabrera are both displayed as “Author, maintainer”

Why

R packages can only list one person with the cre maintainer role in Authors@R. Both Francisco and Carmen maintain the project, so this PR uses pkgdown display customization to show both maintainers on the documentation website without breaking package installation or checks.

Verification

• R CMD INSTALL .
• pkgdown::build_home(pkg = ".", override = list(destination = "/private/tmp/debiasr-maintainer-preview"), quiet = TRUE)
• inspected /private/tmp/debiasr-maintainer-preview/index.html and confirmed the homepage Developers sidebar lists both Francisco Rowe and Carmen Cabrera as “Author, maintainer”

According to the official ⁠CRAN Repository Policy, an R package must show both the name and email address of a single designated maintainer.

[carmen-cabrera]

Agreed. For package metadata, just one maintainer is allowed. But the display on the vignettes can be customised to add more than one. See description above.

Thanks, Carmen. I agree with the approach of keeping this as a pkgdown-only display change rather than changing DESCRIPTION.

One small wording tweak would make this clearer and safer with respect to CRAN conventions. CRAN package metadata expects a single designated package maintainer in Authors@R with the cre role and an email address. Since Francisco remains the only cre maintainer in DESCRIPTION, I suggest avoiding the same plain “maintainer” label for both people in the pkgdown sidebar.

Could we update the sidebar text to distinguish the formal package maintainer role from broader project maintenance, for example:

Francisco Rowe<br>
<small class="roles">Author, package maintainer</small><br><br>
Carmen Cabrera<br>
<small class="roles">Author, project maintainer</small>

That keeps the intent of the PR, recognises both roles on the documentation site, and avoids implying that the package has two CRAN/DESCRIPTION maintainers. Leaving this PR open for that wording change.

@fcorowe agree your suggestion! Feel free to make the suggested changes and commit them to this branch.

Looks good @fcorowe - feel free to merge into main

Approved. The final wording keeps DESCRIPTION CRAN-safe while documenting both project roles on the pkgdown site.
