We shouldn't be setting `placeholder=blur` styles when JS is disabled because we'll have no way to know when the image is loaded and it will be stuck in blur permanently as mentioned in [this comment](https://github.com/vercel/next.js/pull/19052#issuecomment-882886068).
This PR avoids blur styles on the `<noscript>` version of the image.
* Update next-image-unconfigured-host.md
the docs are misleading because I tried this and still got yelled at by compiler, and then added domains and it worked?
* Update next-image-unconfigured-host.md
* Update next-image-unconfigured-host.md
* Update next-image-unconfigured-host.md
* Update next-image-unconfigured-host.md
* Update next-image-unconfigured-host.md

* remove unrelated section

In a previous PR (#27200), we added `minimumCacheTTL` to configure the time-to-live for the cached image. However, this was setting the `max-age` header.
This PR ensures that `minimumCacheTTL` doesn't affect browser caching, only the upstream header can affect browser caching.
This is a bit safer in case the developer accidentally caches something that shouldn't be and the cache needs to be invalidated. Simply delete the `.next/cache/images` directory.

This updates the PR stats action to add the `--network-timeout 1000000` flag when doing initial `yarn` installation to hopefully prevent the random `yarn` failures while it's running. Thanks @styfle for the tip!

Fixes#27252 by using a named function rather than an arrow function. If this is the correct fix, then modifications are also needed for the `layout-component` example, but I'm just providing this one modification right now in case this fix is incorrect.
Fixes inline scripts being duplicated when used with `next/script` component
## Bug

- [x] Integration tests added
## Documentation / Examples
Updated docs to indicate that `id` is needed for inline scripts
This expands on https://github.com/vercel/next.js/pull/27211 and lists the full routes order used in Next.js to allow more exact matching when leveraging the different rewrite priorities.
## Documentation / Examples
- [x] Make sure the linting passes
This adds a note explaining that `beforeFiles` continue instead of checking the filesystem/dynamic routes immediately like they do in `afterFiles` and `fallback`.

* Add x-forward headers to external rewrites
This commit configures the proxy used for external rewrites to include
x-forward headers [1]. This is particularly useful for incremental
adoption, where some routes will be handled by Next.js and others by a
different website. For example, a Rails app will use the
X-Forwarded-Host header to determine which host to use for URL
generation and redirects [2].

This adds a warning when more than 1024 routes are added since it can have performance impacts and includes a document that we can add suggestions to reduce the number of routes being added.

It will allocate 8 lines for preview pages (instead of 4) when they contain slow pages

The right terminology should be used so we don't learn new developers wrong facts.
Using pure function here is plain wrong, the definition of a pure functions is as follows:
> The function return values are identical for identical arguments. The function application has no side effects.
What you have here both have side effects, the calls to `res.setXXX`, and it isn't identical for identical arguments since you have `Date.now()`.

This updates redirects' regexes to not match `/_next` paths since this is currently unexpected and can easily cause a multi-match redirect to break loading client-side assets. This also fixes custom-routes not matching correctly when `trailingSlash: true/false` is used

This adds some missing fields to the `NextConfig` type we expose under `next` and also adds a `NextConfigComplete` internal type that allows us to not treat all fields as optional like you would when using the type in `next.config.js`.

Clean up package.json files in the `examples` directory:
- Add `private: true`
- Remove `version` (because they are irrelevant for packages that are not meant to be published)
- Remove `name` (because they are optional for packages that are not meant to be published, and when someone clones an example, they often rename it and the property becomes stale)
- Remove `author`
- Remove `description`
- Remove `license`
Also remove `with-dynamic-app-layout` example completely, since it does the same as `layout-component` (https://github.com/vercel/next.js/pull/27121#discussion_r668178408).

By itself, `withCoalescedInvoke` with a separate `this.incrementalCache.set(...)` isn't really suitable for streaming responses. Since streaming is asynchronous, updating the cache separately introduces a gap where another origin request for the same resource could be made.
This could potentially be addressed by moving the cache update, but then `IncrementalCache` itself would need to be made to support streaming, in addition to the many other responsibilities it has. In this case, it seemed best to just use composition to add another caching layer in front of it, which is a familiar and understandable concept. Eventually, we might want to move this cache to the HTTP layer, which will also be simpler with this change.
As an added bonus, `renderToResponseWithComponents` becomes significantly simpler, and we delete some duplication.
