Feature: Structured Ingredient Parsing

[nerdstep]

Update the recipe parser to extract ingredient strings into structured components:

• quantity (e.g. 1 1/2, 3, a pinch)
• unit (e.g. cup, tbsp, g, clove, none)
• ingredient or text (e.g. onions, chopped, flour, salt to taste)

Example

Input: "1 1/2 cups chopped onions"
Output:

{
  "quantity": "1 1/2",
  "unit": "cups",
  "text": "chopped onions"
}

Notes

• Handle common edge cases: fractions, ranges (2–3 cloves), compound units (14 oz can), and optional descriptors (to taste, as needed).
• Fallback gracefully if structure is unclear (e.g., store original string).
• This will enable better filtering, measurement conversions, and nutrition integration.
