Claude 92ebd74011 fix: resolve a2ui-root CustomElementRegistry error under React Strict Mode ...

`@a2ui/lit` registers the "a2ui-root" custom element via Lit's
@customElement decorator as a side effect when its UI module loads.
React Strict Mode double-mounts components, and since
customElements.define() is irreversible, the second mount throws:
"the name a2ui-root has already been used with this registry"

Several a2ui-renderer files used value imports from "@a2ui/lit" when
only types were needed, pulling in the full module tree including
the custom element registration. Changed to `import type` where
possible and switched to the narrower `@a2ui/lit/0.8` subpath
(core.js only, no UI/custom element registration) where value
access is needed.
