fix(ci): check only commit title for skip patterns (#46)

* fix(ci): check only commit title for skip patterns

The workflow was incorrectly checking the entire commit body for [skip ci]
patterns, causing false positives when the body mentioned these patterns
in documentation.

Fixed by:
- Check only commit title (first line) for skip patterns
- Use git log --pretty=%s instead of %B for skip detection
- Still use full body for version bump type detection

This prevents false positives while maintaining loop prevention.

* chore: trigger CI checks
