refactor: Simplify template logic - reduce from 6 to 3 categories, remove variant_type, keep validation, remove tests

Simplified template logic: reduced from 6 categories (required, modifiers, optional, versioned, conditional, flags) to 3 categories (required, modifiers, optional). Removed variant_type and replaced with modifier-based approach (version, bootloader replaced, hardware_support). All validation methods kept for recipe generation and validation. Removed tests directory (tests/test_recipe_generator.py, tests/integration/, tests/container/). Removed non-ISO workflows (validate-recipes, test-generation, container-tests, validate-ingredients). Updated Makefile, requirements.txt, and documentation. All 20 recipes successfully generated, validated, and flattened.
