As per React 18 recommendation, we should use e.g. `renderToReadableStream` whenever we use `createRoot`. This is particularly important for currently supported suspense features like `React.lazy` to work properly during SSR.
However, unless you have opted in to streaming support (via [the `runtime` flag](https://github.com/vercel/next.js/pull/34068)), we will wait until `onCompleteAll` before sending it (via the `generateStaticHTML` flag).

Fixes#33879
The `export default xxx` statement is slightly different from estree when exporting an arrow function instead of identifier in swc.
We also need to capture arrow exports.

I've added the test for this but it passes either way, even when the change to loadable.js is not made. On the reproduction I was able to reproduce it consistently and it's fixed with this change.

Make the external `Router` state immutable, and make it so there's only one place (`set`) where it is changed and announced. This is to prepare for #33919, which ensures that we only create a new router once per tree.
Given we've spent a ton of time testing and fixing minifier bugs the majority of cases should now be covered.

Fixed lazyRoot functionality (#33290). Changed the unique id for Intersection Observers discrimination since previously they were only identified by the different rootMargins, now each being identified by the rootMargin and the root element as well
Added more Images to the test with different margins and with/without lazyRoot prop. Browser correctly initially loading two of the four Images according to the props' specifications.

The lock and stale actions will always fail on fork repos since they are using secrets that are not shared with the fork workflow runs.

* Allow scroll prevention on hash change
Currently, `scrollToHash` is performed on every hash change, even when this change is caused by `<Link scroll={false} {...props} />`.
This change prevents scrolling in this case and allows users to specify the desired scrolling behavior in the router's `hashChangeComplete` event.
* Add test case and apply fixes

Currently, if you render `next/link` like
```ts
<Link>
<CustomComponent />
</Link>
```
and have
```tsx
interface Props {
onClick?: () => void; // <— note we're not passing event as an argument
}
function CustomComponent({ onClick }: Props) {
return <div onClick={() => onClick?.()}>Hello</div>
}
```
It'll result in error

## Description
This year we implemented the new Apollo config using this example. We recently moved to `getServerSideProps` as well, however, this was giving us some cache problems. The issue was that the cache was older than the actual data that was coming from the server side query.
Because the `merge` of the cache in `apolloClient.js` is merging the existingCache in the initialState it will overwrite the "fresh" initialState with properties that already exists. This means that if you have something in your cache from previous client render, for example `user` with the value `null`, and you go to a new page and do a new query on the server which returns a value for the `user` field, it will still return `null` because of that `merge` function.
Since this was weird in our opinion, we've changed this in our own environment by always overwriting the existing cache with the new initialState, so that the initialState that is coming from a fresh server side query is overwriting. We thought it was a good idea to reflect this also in this example, because we couldn't think of a reason why the existing cache should overwrite fresh queries.
I've added a reproduction that shows what this is exactly about. I hope my description makes sense, let me know what you think!
## Reproduction of old scenario
Created a reproduction branch here: https://github.com/glenngijsberts/with-apollo-example. Using a different API than in the example, because of https://github.com/vercel/next.js/issues/32731.
1. checkout the example
2. yarn
3. yarn dev
4. visit http://localhost:3000/client-only
5. Hit "Update name". This will run a mutation that will update the cache automatically. Because I use a mocked API, the actual value on the API won't be updated, but this is actually the perfect scenario for the problem because in reality data can already change in the meantime when you're doing a new request.
6. Go to the SSR page
7. This will display two values: one is coming from the server side request (which is the latest data, because no cache is used in `getServerSideProps`) and the other is using the cache, which is outdated at that point, yet it's still returned because the old way of merging the cache was picking the existing cache over the initialState that was coming from the fresh server side query.

## Bug
- Partially fixes#25854
- Badly specified package dependency version (`graphql-let`). The new major version required manual migration. As specified [here](https://github.com/piglovesyou/graphql-let/releases/tag/v0.18.0).
- In `lib/resolvers.ts`
```Module '"*.graphqls"' has no exported member 'MutationResolvers'. Did you mean to use 'import MutationResolvers from "*.graphqls"' instead?ts(2614)```
## Fixes
- Migrate as described in migration guide for `graphql-let` above.
- Update some npm packages along the way.

as handle() returned from app.getRequestHandler() is a Promise, it has to be handled correctly. Simply returning it, works fine.

The recommended code for `_middleware.ts` does not work in prod, but does work locally. You need to use `request.nextUrl.pathname` to properly redirect from what I can tell. You also need to have a quick helper function to strip off the `/default` locale at the start of the pathname as we are providing `/en` as a fallback locale.
FWIW - I am pretty new to NextJS. Someone with more experience should probably review this suggestion before merging it. What I can tell you however is that the code as it is in `_middleware.ts` works locally but breaks in prod. To test this out use the code and navigate to `https//www.mysite.com` - it will work as expected on the root url, as this matches `nextUrl.href`. Now try navigating to `https//www.mysite.com/about` and you will be redirected to `https://www.mysite.com/en/https://www.mysite.com/about`.

I was reading the docs and got nervous. It looked like middleware didn't support async/await. After digging into the examples I found out it is possible.
Not 100% sure if this is the docs change yahs want, but I thought I'd open a PR just incase.
