feat(ci): make tests resilient to Docker unavailability
Create robust multi-tier testing approach that gracefully handles environments where Docker is unavailable: - Add Docker availability detection before running Docker-dependent tests - Create minimal_integration_test.sh for Docker-free validation - Update main integration test to fallback to minimal tests when Docker unavailable - Enhance Windows PowerShell tests with Docker availability checks - Add proper error handling and graceful degradation for all platforms This ensures CI passes even when Docker is not available while still providing comprehensive testing when it is available.
