fix: Include SPA dist folders in production build

Problem: Production zip was only 692K instead of expected 2.5MB+
Root Cause: Global --exclude='dist' was removing SPA build folders

Solution:
- Removed global dist exclusion
- Added specific exclusions for dev config files:
  - tailwind.config.js/cjs
  - postcss.config.js/cjs
  - .eslintrc.cjs
  - components.json
  - .cert directory

Result:
✅ Production zip now 5.2M (correct size)
✅ Customer SPA dist included (480K)
✅ Admin SPA dist included (2.6M)
✅ No dev config files in package

Verified:
- Activation hook creates pages with correct shortcodes:
  - [woonoow_shop]
  - [woonoow_cart]
  - [woonoow_checkout]
  - [woonoow_account]
- Installer reuses existing WooCommerce pages if available
- Sets WooCommerce HPOS enabled on activation
