Move the Community Friends section from the main README into a dedicated
docs page at docs/community/friends.md, following the same structure as
the Reference section.
- New: docs/community/friends.md with content from README
- Updated: docs/toc.yml with Community section and Friends entry
- Updated: docs/docfx.json to include community/*.md in content glob
- Updated: README.md to link to the new docs page instead of inline list
