Added a 'Load directions from a recipe' dropdown to DoughCalc, completing the round trip -- previously Save-as-Recipe could only write TO the Recipes app, never read from it. Only title+directions load, not ingredients/amounts, since most recipes (like the Sandwich Bread) aren't baker's-percentage style the way the calculator works -- flagged in the app's own UI text. Confirmed the fetch+parse logic against real recipe #29.
