feat: add -v short parameter support for version display

- Add -v short parameter alias for --version in both main and dev CLI
- Update Commander.js version configuration to support both -v and
  --version
- Add comprehensive test cases for -v parameter in development and
  production modes
- Add test to verify -v and --version produce identical output
- Update test suite description to reflect broader version testing
  scope

This allows users to use the more concise 'commit-msg -v' command to
quickly check the version number.
