feat: Create customer-spa core foundation (Sprint 1)

Sprint 1 - Foundation Complete! ✅

Created Core Files:
✅ src/main.tsx - Entry point
✅ src/App.tsx - Main app with routing
✅ src/index.css - Global styles (TailwindCSS)
✅ index.html - Development HTML

Pages Created (Placeholders):
✅ pages/Shop/index.tsx - Product listing
✅ pages/Product/index.tsx - Product detail
✅ pages/Cart/index.tsx - Shopping cart
✅ pages/Checkout/index.tsx - Checkout process
✅ pages/Account/index.tsx - My Account with sub-routes

Library Setup:
✅ lib/api/client.ts - API client with endpoints
✅ lib/cart/store.ts - Cart state management (Zustand)
✅ types/index.ts - TypeScript definitions

Configuration:
✅ .gitignore - Ignore node_modules, dist, logs
✅ README.md - Documentation

Features Implemented:

1. Routing (React Router v7)
   - /shop - Product listing
   - /shop/product/:id - Product detail
   - /shop/cart - Shopping cart
   - /shop/checkout - Checkout
   - /shop/account/* - My Account (dashboard, orders, profile)

2. API Client
   - Fetch wrapper with error handling
   - WordPress nonce authentication
   - Endpoints for shop, cart, checkout, account
   - TypeScript typed responses

3. Cart State (Zustand)
   - Add/update/remove items
   - Cart drawer (open/close)
   - LocalStorage persistence
   - Quantity management
   - Coupon support

4. Type Definitions
   - Product, Order, Customer types
   - Address, ShippingMethod, PaymentMethod
   - Cart, CartItem types
   - Window interface for WordPress globals

5. React Query Setup
   - QueryClient configured
   - 5-minute stale time
   - Retry on error
   - No refetch on window focus

6. Toast Notifications
   - Sonner toast library
   - Top-right position
   - Rich colors

Tech Stack:
- React 18 + TypeScript
- Vite (port 5174)
- React Router v7
- TanStack Query
- Zustand (state)
- TailwindCSS
- shadcn/ui
- React Hook Form + Zod

Dependencies Installed:
✅ 437 packages installed
✅ All peer dependencies resolved
✅ Ready for development

Next Steps (Sprint 2):
- Implement Shop page with product grid
- Create ProductCard component
- Add filters and search
- Implement pagination
- Connect to WordPress API

Ready to run:
```bash
cd customer-spa
npm run dev
# Opens https://woonoow.local:5174
