feat(host): editorRegistry — dispatch editor surfaces by product.editorKind

Increment 1 (goods, zero behavior change): mirror template-manager's
editor-neutrality seams on the host so a second editor (e.g. sign-studio)
can be added as an adapter instead of by re-touching mount sites.

- src/editors/editorRegistry.js — getEditorAdapter(editorKind); NO goods
  fallback for an unregistered kind (mirrors the CMS's validator rule).
- src/editors/goods/GoodsCustomizer.jsx — the customer ApparelDesigner
  mount, extracted from CustomizeRoute (goods branding + view/entry
  derivation moved into the adapter).
- src/editors/goods/GoodsAdminEditor.jsx — the former AppRouter
  AdminEditorCanvas, moved verbatim.
- CustomizeRoute + AppRouter renderCanvas now dispatch on
  product.editorKind (default 'goods'). App.jsx confirmed dead (main.jsx
  renders AppRouter), so only 2 live mounts change.

Verified: vite build clean; the /customize customer surface renders and
is interactive on an alternate-port smoke, no React errors. The admin
surface is a verbatim move (build/import-verified; its interactive render
sits behind admin SSO). editorKind resolves to 'goods' until the CMS
surfaces it on the public template/variant response (Increment 2).
