Archive and disable Snipcart integration for Shopify migration

Disable Snipcart e-commerce integration to prepare for Shopify Buy Button. All Snipcart code is preserved in assets/snipcart-archive/ with complete restoration instructions.

Changes:
- Comment out Snipcart SCSS import
- Disable Snipcart routes (validate.json, webhook)
- Comment Snipcart attributes in product template
- Remove Snipcart scripts from footer
- Create archive with snipcart.js, product-size.js, _snipcart.scss
- Add comprehensive README.md with restoration guide
