ci: improve GitHub Actions workflow and add code quality checks

- Remove dependency on real API tokens in tests
- Add multi-Ruby version testing (3.0, 3.1, 3.2)
- Implement test coverage reporting with SimpleCov
- Add RuboCop for code style enforcement
- Add Brakeman for security analysis
- Add bundle-audit for dependency security checks
- Add Dependabot configuration for automated updates
- Configure caching for faster CI builds

Breaking Changes:
- Tests now use WebMock instead of real API calls
- Require Ruby >= 3.0

Testing:
- Use dummy API key for all test runs
- All API calls are now mocked with WebMock
- Coverage reporting through CodeClimate

Configuration:
- Add .rubocop.yml for code style
- Add dependabot.yml for dependency management
- Update gemspec with new development dependencies
