fix: rollback version from 5.0.0 to 4.3.0 and improve lint-staged config

- Reset both package.json files to version 4.3.0
- The v5.0.0 bump was accidental due to BREAKING CHANGE in commit message
- Enhanced lint-staged to check all YAML files in project including .bmad-core/
- This ensures husky catches YAML formatting issues before push
