v0.2.2

Fixed

• Container builds now use Poetry 2.2.1 so PEP 621 project metadata is accepted during image publication.

Validation

• poetry check --lock
• poetry run pre-commit run --all-files
• poetry run pytest
• poetry build

Note: local Docker build could not run because Docker Desktop's Linux engine was unavailable on the workstation; the tag-triggered GitHub Actions container workflow is the release verification path for this fix.
