feat(demo): grocery scan demo with ingredient check (stethoscope) mode - #283
Merged
Conversation
Full UI for scanning a product's ingredient list on camera: - new ScanMode.ingredients (stethoscope dock icon + hint) - capture flow: shutter (stethoscope identity) → scanning stage → on-camera results overlay (never leaves the viewfinder) - IngredientsOverlay: gluten verdict pill (contains/may/free), nutrition score ring, factor breakdown bars, ingredient chips with gluten sources red-flagged, Re-scan / Back to camera - mock package-back scene to frame + MockGroceryProvider.scanIngredients - IngredientsAnalysis model (productName, brand, verdict, score, factors, ingredients, glutenSources) — the AI backend contract when wired (model: 'ingredients', ZikZakScore-style)

Adds the standalone grocery_scan_demo app (apps/grocery_scan_demo) with the full camera UI suite — barcode/text/produce/meat price-compare flows plus the NEW ingredient check (stethoscope) mode:
Verified end-to-end on the Android emulator (dock, capture, overlay, dismiss, re-scan). The zik_zak wiring (upload to MinIO fire-and-forget + base64 AI call + branded overlay) is in progress separately.
