bug: client components can't be named exports, must be default

[hex2f]

The following code currently breaks the bundler, as only default exports are handled.

// components/button.tsx
"use client";

export function SmallButton() {
  return <button>...</button>
}

// pages/index.tsx
import { SmallButton } from './components/button.tsx'

export function Page() {
  return <SmallButton />
}
