v0.3.0
- bump version to 0.3.0 - add the 0.3.0 changelog entry (first PyPI release of the fork), folding the previously unreleased notes into it - add `make publish`: builds and uploads via uv, reading the PyPI API token from the gitignored .pypi-token file; refuses to run while the placeholder is in place Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
