Recommended daily intake by profile API

Compute a personalized recommended daily intake from age + sex (+ optional weight/height/activity): estimated calories (Mifflin-St Jeor BMR x activity), macro split, fiber, water, and vitamin/mineral targets from US DRI reference tables — the value-add being the profile-driven RDI computation. Differs from data/food which is per-food nutrient lookup. Answers 'daily calorie needs for a 30yo male', 'how much protein should I eat', 'recommended iron intake for women', 'RDA vitamins by age'.
