Add publication README and research area classifications

[Copilot]

Publication data lives in data/publications.yaml but contributors often look in content/publications/. Added research area classifications to enable filtering.

Changes

• Added /content/publications/README - Documents publication workflow and YAML schema. No .md extension prevents Hugo deployment.

• Added focus_area to 25 publications - Classified based on abstract/title content into 4 categories:

  • Education & Pedagogy (10)
  • Meta-Research & Scientific Reform (8)
  • Community, Governance & Sustainability (6)
  • Equity, Diversity & Social Justice (6)

• Removed redundant status display - Removed the grey italic status text (e.g., "Published", "Preprint") that appeared next to journal names in publication cards, as this information was redundant.

Example

- title: "Teaching open and reproducible scholarship"
  type: "journal"
  year: "2023"
  # ... other fields ...
  focus_area: "Education & Pedagogy"  # Added

The publication filters in layouts/shortcodes/publication_filters.html already support these classifications.

<issue_description>- Add a README in an appropriate place, ideally in content/publications, but in a way that does not get deployed to website. This should explain where and how to add publications - i.e. in the json in the data folder

• Add research areas to the publications, based on your text understanding. Multiple classifications are ok</issue_description>

@copilot remove the publication status (small in grey next to the journal) - that is redundant

Removed the redundant status display in commit 35fbd52. The grey italic text (e.g., "Published", "Preprint") that appeared next to the journal name has been removed from the publication cards.

Before: Journal Name Published (with grey "Published" text)
After: Journal Name (status removed)

The status information is still stored in the YAML data but no longer displayed on the page.

@richarddushime the redundant "published" style labels are gone in staging, but the new categories don't show up. Is stating somehow relying on the data file from main? Or what is wrong here? Apart from that, this PR would be good to merge.
