feat: generate a complete themed meal from a collection (v0.52.0)
New "Generate meal" button on any owned collection — pick a theme (free text) and 2-6 courses (starter/main/side/dessert/drink), one generateObject call produces a coherent recipe per course (shared cuisine/style, matching flavors across courses) and all of them get saved as real recipes and added to that collection in one action. Follows the meal-plan generation route's established pattern: single withAiQuota charge for the whole generation, then a pre-flight loop charging the tier's recipe limit once per generated recipe (rolled back on a partial breach) before the insert transaction runs. Recipes are tagged with their course name for later filtering; visibility defaults to private like every other AI-generated recipe. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
