`NextRscErrClientMetadataExport` thrown when mixing metadata and virtual css modules

### Link to the code that reproduces this issue https://github.com/jantimon/reproduction-next-server-component-css-error ### To Reproduce 1. clone https://github.com/jantimon/reproduction-next-server-component-css-error 2. npm install 3. npm run dev ### Current vs. Expected behavior I am using a virtual css module (`./page.yak.module.css!=!./page?./page.yak.module.css`). It looks like that this virtual css module is compiled by SWC and fails because it was marked as client component. ``` yarn dev yarn run v1.22.19 $ next dev ▲ Next.js 14.2.4 - Local: http://localhost:3000 ✓ Starting... ✓ Ready in 1491ms ⨯ ./src/app/page.tsx?./page.yak.module.css Error: × You are attempting to export "metadata" from a component marked with "use client", which is disallowed.
