test: add comprehensive pytest test suite
Add complete test infrastructure for yaml2pptx project with 245+ tests covering unit, integration, and end-to-end scenarios. Test structure: - Unit tests: elements, template system, validators, loaders, utils - Integration tests: presentation and rendering flows - E2E tests: CLI commands (convert, check, preview) Key features: - PptxFileValidator for Level 2 PPTX validation (file structure, element count, content matching, position tolerance) - Comprehensive fixtures for test data consistency - Mock-based testing for external dependencies - Test images generated with PIL/Pillow - Boundary case coverage for edge scenarios Dependencies added: - pytest, pytest-cov, pytest-mock - pillow (for test image generation) Documentation updated: - README.md: test running instructions - README_DEV.md: test development guide Co-authored-by: OpenSpec change: add-comprehensive-tests
