chore: align IaC with today's package installs + PDF comparison docs

DevOps sync (2026-05-21):
- Remove onlyoffice-desktopeditors from absent list (actively used)
- Add gnome-keyring, rbw to common role (secrets migration)
- Add perl-image-exiftool, icoutils, innoextract-git to dev-tools
  (Windows installer inspection)
- Create fonts role: Inter, Cascadia Code, Fira, Source Sans, TeX Gyre
- Create pdf role: zathura, zathura-pdf-mupdf, python-weasyprint
- Register new roles in workstation.yml

PDF comparison:
- Add pdf-comparison docs with Quarto/Typst/Pandoc outputs
- Add batch-pdf.sh script
- Update yazi-cheatsheet.md
- Ignore .quarto/ cache
