PR sveltejs#17461 added the `wait` function to `reactivity/async.js` and modified the compiler to generate `$.wait()` calls, but forgot to export it from `index.js`. This causes a runtime error when using `await` inside `$derived()` with `experimental.async: true`: ``` TypeError: $.wait is not a function ``` Fixes sveltejs#17529
