fix(nextjs): Export HandleSSOCallback from @clerk/nextjs

[manovotny]

Description

<HandleSSOCallback /> is re-exported from @clerk/react in packages/nextjs/src/client-boundary/uiComponents.tsx, but it was never added to the explicit client-boundary export list in packages/nextjs/src/index.ts. As a result, import { HandleSSOCallback } from '@clerk/nextjs' fails, and the component can't be used on the SSO callback route of a custom flow (for example, to complete a Clerk Protect challenge after SSO).

This PR adds HandleSSOCallback to that list. The other SDKs that re-export @clerk/react components (@clerk/react-router, @clerk/tanstack-react-start, @clerk/chrome-extension) already export it.

It also adds a snapshot test for the @clerk/nextjs root exports, like the ones those SDKs have, so a missing export shows up as a test failure. The test needed a Vitest alias for the #components subpath import, which resolves to components.client.ts, matching the package's default condition.

📝 Walkthrough

Walkthrough

The @clerk/nextjs root module now exports HandleSSOCallback. A Vitest test checks the sorted root export names against a snapshot. The Vitest configuration maps #components to the client components module. A patch changeset documents the export.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~8 minutes

Merge Risk: 🔵 Low · up to 1bf55

The export and its snapshot appear ready, but the new test should follow the repository’s return-type rule before merging.
