Phase 1: Enhance recipe generator with semantic validation

- Add pykickstart integration for semantic validation
- Support version-specific validation (F42 for Fedora 43, DEVEL for rawhide)
- Track deprecated/removed commands (authconfig, keyboard, langsupport, nfs, parted)
- Add warning for deprecated commands, error for removed commands
- Provide migration suggestions for each deprecated command
- Add --strict flag for CI mode (warnings treated as errors)
- Upgrade validate_recipe_semantic() with enhanced error reporting
- Add _check_deprecated_commands() for command-level validation
- Improve version extraction regex to handle _ and - separators
- Add 5 new test cases for deprecated command detection and version extraction
- Update tests/test_recipe_generator.py with comprehensive validation tests

All 36 tests pass with semantic validation working for generated recipes.
