fix: resolve commitizen configuration issues in GitHub Actions (#28)

* fix: resolve commitizen configuration issues in GitHub Actions

- Replace .cz.json with .cz.toml for Python commitizen compatibility
- Update version to 1.1.0 to match latest tag
- Add debugging information to workflow for better troubleshooting
- Fix 'path argument must be string' error in commitizen

The issue was that Python commitizen expects TOML format config,
not JSON. This resolves the workflow failures where version bump
detection was not working properly.

* style: add missing newline at end of .cz.toml file

Address PR feedback from Gemini Code Assist review.
Follow best practice of ending configuration files with newline
to prevent potential issues with command-line tools and VCS.

* style: fix trailing whitespace in workflow file

Remove trailing spaces from .github/workflows/publish.yml
to satisfy pre-commit trailing-whitespace hook requirements.
