Refactor: implement analyzer interfaces, add Cobra commands, integrate lipgloss styling
- Created analyzer.ResourceAnalyzer and analyzer.Baseline interfaces - Implemented interfaces in SQL and GKE analyzers - Added comprehensive interface tests - Refactored CLI to use Cobra command structure (gcp sql/gke) - Integrated lipgloss for beautiful styled output - Updated all tests to match new styled output - Changed license from Apache 2.0 to MIT - All tests passing with 29% coverage
