feat(plugin): add storefront standards for coding agents

[blurrah]

Summary

• add a build-storefront skill covering rendering dependencies, cache ownership, Suspense boundaries, Server and Client Components, mutations, and commerce-flow verification
• provide focused guidance for home, collection, search, product, cart, and account work without prescribing visual composition
• make Shopify AI Toolkit authoritative for Shopify API facts and validation
• reduce shopify-graphql-reference to Vercel Shop integration guidance and remove the redundant schema wrapper
• align Shopify CMS caching, invalidation guidance, documentation, and rollout metadata

Why

Coding agents should be able to redesign or extend Vercel Shop freely while preserving production-grade commerce architecture.

These skills capture the standards behind the template: non-blocking rendering, coherent caching, narrow client boundaries, correct mutations, and end-to-end commerce behavior, without constraining the resulting visual design.

Shopify API knowledge remains owned and validated by Shopify AI Toolkit. Vercel Shop owns how validated operations integrate with Next.js and Vercel.

No template routes or presentation components are removed or replaced.

Validation

• pnpm --filter docs lint
• pnpm --filter docs typecheck
• pnpm --filter docs build
• official skill validation for build-storefront, shopify-graphql-reference, and enable-shopify-cms
• storefront audit: 0 errors, 6 existing Next.js image-priority review items
