Add recipe generator and dish flattener

- create generate_recipe.py for universal template recipe generation
- support cartesian product expansion from recipes_manifest.yaml
- generate 72 unique recipes with proper filename disambiguation
- update Makefile with simplified validation using ksflatten
- keep ksflatten-relative script as-is for dish flattening

The generator reads recipe_templates.yaml and recipes_manifest.yaml to
produce recipe files that ksflatten then flattens into final dishes.
