fix: externalize subpath imports in library builds for vite 8 compatibility

Rolldown (used by Vite 8) preserves CJS require() calls for non-externalized
dependencies. The external function used exact matching with .includes(source),
which missed subpath imports like "use-sync-external-store/shim/with-selector".
This caused require("react") to fail at runtime in the browser with
"Calling require in an environment that doesn't expose the require function".
