Implements the six previously-unscoped feature ideas plus a mobile layout fix reported via screenshot: - Mobile: Recipes/Collections/Pantry/Meal Plan/Shopping Lists headers now stack and wrap instead of clipping buttons on narrow viewports. - Recipe diff/compare view: word/list diff against any past version, next to Restore in version history. - Shared meal plans & shopping lists: new shoppingListMembers/ mealPlanMembers tables (viewer/editor roles, mirrors collectionMembers), share dialogs, membership-checked routes. - PDF cookbook export: /print/collection/[id] renders a whole collection with page breaks, using the existing print-CSS pattern instead of adding a PDF rendering dependency. - Grocery delivery handoff: shopping lists can copy-as-text (works today) or send to Instacart once INSTACART_API_KEY is configured (stub adapter — real API needs a partner agreement). - Personalized "For You" feed tab: ranks public recipes by tag/ dietary overlap with the user's favorited/highly-rated history. - PWA: added manifest.json + icons on top of the existing service worker so the app is installable; cook-mode pages were already cached for offline use.
