* refactor(create): consolidate create code into a single route group
Move all create code from app/(app)/create and app/(create) into the
nested route group app/(app)/(create), and the preview iframe pages
into app/(view). URLs are unchanged: /create keeps the (app) chrome
(and the header now persists across / <-> /create), /init keeps its
root-level path for the CLI contract, and /preview stays chrome-less
for the customizer iframe.
Registry sources and published payloads are untouched: two temporary
tsconfig path aliases map @/app/(create)/* and the legacy
@/app/(app)/create/* onto the new location. App code imports the real
path.
Also inline parse-config and build-instructions into the create lib so
the init routes are thin HTTP handlers, and remove the icon-placeholder
and lib re-export shims.
