Add integration tests for RHI module: - Add tests/RHI/integration/ directory with CMakeLists.txt - Add RHIIntegrationFixture for shared test utilities - Add minimal integration test (window creation, basic rendering) - Add compare_ppm.py for image comparison - Add run_integration_test.py test runner script These integration tests verify the complete rendering pipeline by comparing rendered output against ground truth PPM files.
