chore: release 0.2.1

Cut the 0.2.1 release:
- Date the changelog section (2026-06-13).
- Bump pyproject.toml to 0.2.1 so a `v0.2.1` tag passes the publish
  job's tag/version assertion.
- Bump the _version.py fallback to 0.2.1 so __version__ and the client
  User-Agent report 0.2.1 in source/vendored checkouts without installed
  package metadata (importlib.metadata.PackageNotFoundError path).
