v0.7: shop storefront + routed app

AppRouter replaces the single-page App as the mounted root: shop routes
(/ and /shop → ShopHome, /shop/:productSlug → ProductPage, /cart →
CartStub, /customize → CustomizeRoute) plus the template-manager admin
surfaces (/admin/templates|products|featured|trash, v0.8 adds
/admin/inventory + RequireAdmin wrapping). App.jsx stays on disk one
release as the documented legacy fallback — nothing imports it.

New shop UI: components/shop/ (ShopHome/Hero/ProductGrid/ProductCard/
ProductPage/ProductGallery/ProductInfo/ProductBuyPanel/CartStub/
ShopHeader/TemplateGalleryForProduct), hooks (useShopProducts/
useShopProduct/useCart/useFacetCatalog), and shop.css + admin.css.

Header gains the module-gated Clear button (onCanClearChange /
onElementCountChange mirror the editor module's history-commit
signals); i18n keys follow. vite proxies /products to the Node server
(template-manager serves product imagery — without it the SPA fallback
returns index.html as an image) and adds a template-manager chunk.
