Mike Kell 747d917aed feat(pantry): complete Phase 5 pantry delta engine and auto-shopping generator
Domain (pure Dart):
- Add PantryItem and ShoppingListItem entities plus the PantryCategory aisle
  enum (produce/meat_seafood/dairy/dry_goods/spices/other) with a keyword
  infer() heuristic and ExpirationStatus warning buckets (expired /
  expiringSoon within 3 days)
- Add measurement_units value object (mass/volume/count dimensions with
  lb/oz/g/kg and ml/l/tsp/tbsp/cup conversion onto a shared base scale) and
  ingredient_name canonicalizer (lowercase, parenthetical stripping,
  plural folding: eggs -> egg, lbs -> lb)
- Define IPantryRepository contract covering inventory and checklist CRUD
- Add CalculateShoppingDelta use case: aggregates the active 7-day meal-plan
  slot window's recipe ingredient manifests by canonical name, computes
  deficit = totalRequired - currentPantryQuantity in base units (dominant
  recipe unit wins display, 2-decimal rounding), upserts isAutoGenerated
  rows with stable ids and source recipe titles, clears stale auto rows once
  stock covers the plan, and never modifies or removes manual rows

Data:
- Bump AppDatabase to schema v4 (migration for v1-v3 installs) with
  PantryItemsTable (UUID PK, canonical name, quantity/unit, aisle key,
  nullable expirationDate, lastUpdated) and ShoppingListItemsTable (UUID PK,
  required quantity/unit, purchased/auto flags, JSON sourceNotes for recipe
  titles) plus watch/get/upsert/delete helpers
- Implement DriftPantryRepository (record <-> entity mapping, enum keys,
  JSON recipe-title round-trip)

Presentation:
- Add PantryInventoryController (live watch stream, quick +/- stock steps
  clamped at zero, aisle-grouping vs expiration-sort modes) and
  ShoppingListController (manual add, All/To Buy/Checked filter, check-off
  with "Add to Pantry?" unit-converting stock merge or aisle-inferred row
  creation, syncWithMealPlan reading the planner's Monday-Sunday window and
  recipe catalog)
- Refactor PantryScreen: Inventory/Shopping tab header with remaining-count
  badge, Aisles/Expiration segmented control, categorized tiles with +/-
  counters and expired/expiring badges, swipe-to-delete on both lists,
  prominent "Sync with Meal Plan" banner with run summary + snackbar,
  "From: <recipe>" origin chips on auto rows, checklist filters, check-off
  -> pantry prompt, and Add Pantry Item / Add Shopping Item dialogs

Testing:
- 10 new tests in delta_calculator_test.dart: 300 g on hand vs 800 g
  requirement -> +500 g entry, sufficient stock -> no entry, manual rows
  preserved across repeated syncs, stale auto cleanup, cross-recipe
  plural/unit normalization (4 eggs + 2 egg - 2 -> +4 egg), lb/oz scale
  unification (0.75 lb), check-off -> pantry transfer (merge +
  aisle-inferred create), end-to-end syncWithMealPlan, and inventory
  canonicalization / quick-adjust clamp; full suite green (99/99)
- flutter analyze clean (No issues found!) after codegen; BUILD_STATE.md:
  mark Phase 5 complete and record all verification gates
