### What?
Note: This is not a breaking change, just removing some unused code.
### Why?
Since #56896 we don't need this, as Node.js 18+ has `fetch` exposed by default.
### How?
Depends on #56896, #56909
We already didn't load `fetch` if `globalThis` had it (ie. Node.js 18+ environments), and since we are dropping support for Node.js 16, these code paths should have no effect on runtime behavior.
### Story
Since we introduced `ImageResponse` into `next/server` export, there're a few libraries relying on `next/server` that accidentally ended up with bundling og image into the bundle. As og package is quite large that could easily raise the size concern for middleware, edge runtime routes.
### Struggles
We've done optimizations. The tree-shaking strategies are tricky, we tried modularize imports and also optimize cjs require/exports to make sure you're not including og package into bundle if it's not being used. However, it's still not 100% can handle all the bundle optimization cases, such as `import {..} from "next/server.js"` could also ended up with the cjs bundle that failed the tree-shaking.
### Move on
So we decide to move og `ImageResponse` into a separate export `next/og`
Closes NEXT-1660
This avoids testing against latest exact canary version as this causes these tests to fail while the publish is still in progress. As a follow-up we can investigate moving this post publish or packing/deploying tarballs to use.

This PR adds the optional `limit` parameter on String.prototype.split uses.

While the performance gain may not be significant for small texts, it can be huge for large ones.
I made a benchmark on the following repository : https://github.com/Yovach/benchmark-nodejs
On my machine, I get the following results:
`node index.js`
> normal 1: 570.092ms
> normal 50: 2.284s
> normal 100: 3.543s
`node index-optimized.js`
> optmized 1: 644.301ms
> optmized 50: 929.39ms
> optmized 100: 1.020s
The "benchmarks" numbers are :
- "lorem-1" file contains 1 paragraph of "lorem ipsum"
- "lorem-50" file contains 50 paragraphes of "lorem ipsum"
- "lorem-100" file contains 100 paragraphes of "lorem ipsum"
This updates some code related to web streams and encoding.
- Removes some unused code related to base64 encoding/decoding (Edge runtime currently supports it natively via `Buffer`)
- Prefer readable stream `pull` versus `.on("data", (chunk) => { ... })` event handlers (simplifies execution)
- Utilize `pipeTo` and `pipeThrough` on web streams to remove custom code related to stream pumping
- Updates pipe readable function to utilize web streams first class rather than relying on manual pumping + stream management
- This also takes advantage of the `AbortController` when piping so that the response can use it to cancel the stream
### Reason for making this change
https://yarnpkg.com/getting-started/qa#:~:text=yarn%2Finstall%2Dstate.,your%20workspaces%20all%20over%20again.
In the official documentation of `yarn`, it is stated that `.yarn/install-state.gz` is an optimization file that developer shouldn't ever have to commit. However, currently, when running `create-next-app`, `.yarn/install-state.gz` is being commited.
### Remaining work
I apologize for only modifying one template initially to initiate the discussion first.
If this change is agreed upon, it should be synchronized with other `.gitignore` templates. Would it be possible to follow a similar approach as in https://github.com/vercel/next.js/pull/47241? I would appreciate any assistance in syncing this change.
We currently log when a worker is restarted but not when we send the kill signal, which can create a delta in logs of cryptic errors while the worker is exiting. This explicitly logs when we're terminating the static worker prior to a restart, and also adds an optional logger fn so that we pretty-print the messages.

## History
We used to pass `onLoad` through directly to the underlying img so `onLoadingComplete` was introduced in order to handle the case when `placeholder="blur"` was used and `onLoad` would trigger before the placeholder was removed.
We have since changed the behavior of `onLoad` so that it acts the same as `onLoadingComplete` and therefore `onLoadingComplete` is no longer needed.
## What is this PR doing?
This PR marks `onLoadingComplete` as deprecated in favor of `onLoad`. In the future, we may remove `onLoadingComplete`.
I think some of the runners are missing `yarn` globally installed so its attempting to install with corepack. But the default behavior of corepack is to use the repo version (pnpm in this case) so running `yarn` will error. This PR disables corepack strict mode to avoid that problem.
The PR follows #56536 and #56491, replacing `fs-extra` usages inside the `scripts/` folder.
Note that the `copy` and `move` haven't been replaced yet. Currently, there is no better recursive copy (lightweight, promise-based, Node.js built-in `copyFile` API-based, support the `filter` option) library alternative available on npm, and Node.js built-in `fs.rename` doesn't support `overwrite`.
The PR also replaces many async fs API usage with their sync versions.

In an attempt to avoid introducing experimental features into the Next.js userland space, we're reverting the `Promise.withResolvers` polyfill and preferring an internal `DetachedPromise` interface.
This PR introduces a new API, `unstable_noStore`, which will allow users to declaratively opt out of caching anywhere during static generation in the same way that you can specify `cache: 'no-store'` on a fetch call in Next.js.
An important caveat and difference from just calling `cookies()` to opt-out of static generation is that this won't opt you out when called from within `unstable_cache` and instead defers to the cache configuration to it.
```
import {unstable_noStore as noStore} from 'next/cache';
export default async function Component() {
noStore();
const result = await db.query(...);
}
```

### What?
### Why?
### How?
Closes NEXT-
Fixes #
-->
This PR therefore introduces to always set response status code to 500
unless it is a `NotFoundError` or `RedirectError`. This PR would fix
issue #56235. See also:
https://codesandbox.io/p/sandbox/nice-panini-2z3mcp .
**Current Behavior**
At the moment, when an unexpected error occurs during app server
rendering, a 200 ok is returned as status code. This seems to be
undesirable because of the success status CDNs will cache the error
pages and crawlers will index the page considering the error content as
the actual content.
**Desired Behavior**
This issue is related to discussion
https://github.com/vercel/next.js/discussions/53225. Even though I
understand that the response status code cannot be set if streaming has
started, in my view it would be best to set the response status to 500
whenever it can (so before the streaming has started) for SEO and (CDN)
http caching. This would also be consistent with how 404s currently
work; that is, response status code is set to 404 if `NotFoundError`
occurred before streaming (related
[issue](https://github.com/vercel/next.js/issues/43831) &
[PR](https://github.com/vercel/next.js/pull/55542)).
Ideally, when a runtime error happens after streaming, a `<meta
name="robots" content="noindex" />` would also be added. But I didn't
want to make the PR too complex before receiving feedback.

follow up to #56898 where I noticed that we don't apply any filtering to the trace files for the user routes, resulting in files that would need to be filtered like `caniuse` not being filtered out correctly. This fixes that.
A lambda in my test project goes from `2.7MB` to `1.4MB`
followup: add some snapshot tests

### What?
Update Babel packages across the board
### Why?
Since you ship vendored presets and plugins it's impossible for people to update this stuff at their own pace - independently from Next. So users of `next/babel` are currently stuck with old versions and, for example, they might not be able to use the TS `satisfies` operator.
### How?
I just updated ranges (to pinned ones) where I could find them, run `corepack pnpm i` and re-run build scripts in the `packages/next`.

### What?
BREAKING CHANGE: Bump the minimum required Node.js version.
### Why?
Node.js 16 has reached end-of-life in September.
Bumped to `18.18.2` since it contained some security-related patches: https://nodejs.org/en/blog/vulnerability/october-2023-security-releases
### How?
Bumped `engines` where needed, upgraded the workflows.
This will allow us to remove quite a few polyfills, I'll open separate PRs for those.
