Unify Research & Resources into single page (#101)

Added Zenodo Community and GitHub Repositories sections to pubs.qmd,
matching Hana's wireframe which shows all research outputs on one page.
Sidebar links now point to anchor sections instead of external URLs,
so users get context before clicking through.

Closes #96
