chore(reset)!: strip storefront → network-service seed (v0.9.0)

Pivot ecomm from a generic multi-tenant Shopify-alternative storefront to the
commitment-commerce + cross-maker verified referral NETWORK direction
(ecomm-content/rfcs/network_strategy.md; OHM identity/relationality super-drafts).

Phase A of the reset — clear the decks:
- Strip the storefront surfaces with no carry-forward: the storefronts domain,
  the products import/export/image HTTP spine (service/imagefetch/repo + endpoints),
  the SPA frontend, and the Playwright e2e suite.
- Keep the reusable core: /healthz + /api/auth/* (accounts); the
  catalog-normalization library (codec/dialect/models/serialize/validate/diff/hosted —
  importable, no HTTP yet); platform/* infra. Migrations untouched (append-only).
- Reduce check.sh to backend-only (import-linter + pytest); trim dev.sh and the unused
  GCS overlay env. Repoint app.json/README/CLAUDE.md; bump VERSION 0.8.0 -> 0.9.0.

check.sh green: import-linter (main > domains > platform) KEPT, pytest passing.
