If there's a build error on initial page load, the error is sometimes displayed as a server error instead of a build error:
![image](https://user-images.githubusercontent.com/25056922/220099125-5f538551-342f-4bca-a670-a04d8428de2d.png)
When the hot reloader sends the `sync` event to the client, it always picks the latest compilation. The problem occurs if only the server has errors and the client is the latest. In that case the server errors are ignored and the client stats are sent instead.
This PR makes it check if the server compilation has errors, if that's the case we use those stats. `built` events acts the same, new client builds are [ignored if the server has errors](https://github.com/vercel/next.js/blob/canary/packages/next/src/server/dev/hot-middleware.ts#L123.):
```ts
onClientDone = (statsResult: webpack.Stats) => {
this.clientLatestStats = { ts: Date.now(), stats: statsResult }
if (this.closed || this.serverLatestStats?.stats.hasErrors()) return
this.publishStats('built', statsResult)
}
```

If the children being rendered output more than a single text node in aggregate the browser will display markup and comments as text in the title and hydration will likely fail and fall back to client rendering

There are two edit point
First, The url in the doc directed wrong URL.
Second, The instruction in the doc says "Make sure linting passes (you
can run pnpm lint-fix)"
But PR request user to check "Make sure the linting passes by running
`pnpm build && pnpm lint`"
I thought that it need unity and if i run pnpm lint-fix, lots of errors
appear.
So i edit instruction from `pnpm lint-fix` to `pnpm build & pnpm lit`

This adds `loader-runner` to the compiled packages distributed with
Next.js
This is a dependency of Turbopack's webpack loader support. Currently,
users have to manually install `loader-runner` in their application to
use webpack loaders with Turbopack. This will allow Turbopack to require
loader-runner from within the installed version of Next.js instead.
Test Plan: `require('./packages/next/dist/compiled/loader-runner/')`

Currently the export conditions we use for certain runtime, in different
places of the config are totally random. This PR unifies them by
referring to the single constant.
Also adds `worker` as a condition of the edge runtime.

Fixes NEXT-583
Ran into this when looking into adding an integration test for the RSC
normalizing PR.
Middleware has the ability to override `headers` which causes
client-side navigation to break as it'll remove the `rsc` header which
causes Next.js to respond with the HTML response instead of the RSC
payload.
This PR ensures the RSC headers are always copied over as middleware
does not get access to them.

Fixes#45883
Fixes NEXT-541
The reason the url after normalization in middleware ended up being
`/somethingabc=def` instead of `/something?abc=def` is that the regex
matches `?` so the `?` will be removed. Since it's in a capture group
the only change needed was applying that by adding `$1` to the
replacement.
Added some unit tests for this function, going to add additional
integration tests now.

This PR fixes `next/image` codemods and makes sure that the tests are properly testing the codemods using the `tsx` parser. This is accomplished by make sure each codemod declares the `tsx` parser instead of the CLI.
