Summary

  • Move the 31-entry All Contributors roster from trvny/trvny to the shared profile README.
  • Add .all-contributorsrc here as the canonical configuration (projectName: .github).
  • Keep original activity links in the existing table; the generated cross-repo contributors SVG remains separate.

Source cleanup follows in trvny/trvny after this lands.
