Here is the error when building @libsql/client:

Here is the [codesandbox](https://codesandbox.io/p/sandbox/nice-feynman-hwjsyd?file=%2Fapp%2Fapi%2Froute.ts%3A8%2C7) to repro it.

Enable the `serverComponentsExternalPackages` the issue will be gone:

This PR just adds it to the default package list, so Next.js developers don't have to add it manually.
