Move all business-logic packages from internal/ root into internal/domain/: auth, cuisine, diary, dish, home, ingredient, language, menu, product, recipe, recognition, recommendation, savedrecipe, tag, units, user Rename model.go → entity.go in packages that hold domain entities: diary, dish, home, ingredient, menu, product, recipe, savedrecipe, user Update all import paths accordingly (adapters, infra/server, cmd/server, tests). No logic changes. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
