Save a meal the person asked to log or plan. Find each food with list_foods first and pass a match as food (its library and key); use newFood only when nothing matches, never for a product the catalogue has. If the food or portion is unclear, ask one short question first (for example: chicken or bean burrito, and one or two?), without asking again for what the person already said. Use state logged for food eaten, and planned only for a plan the person asked to save, since suggestions alone are not a request. To log a meal that was planned, use update_meal instead of creating another. For planning, read get_targets first and respect the diet, dislikes and allergies the person mentions. Pass photos the person attached as photos. Say the meal is saved only after this returns its id; after an error or timeout, check list_meals for that day before trying again.
