chore(release): v2.1.0

[pactflow-ci-bot]

Important

VERSION and CHANGELOG.md are the source of truth, not this title
or description. The release tag is created from VERSION as it exists in
the merge commit. To override either, push a commit to this branch before
merging — but note that any subsequent push to main resets this branch
and discards manual changes.
