This PR introduces breaking changes by renaming components.
- Rename `next/image` to `next/legacy/image`
- Rename `next/future/image` to `next/image`
The diff is very confusing because both components are very similar so git got confused.
Adds `next/navigation` and `next/headers` APIs. Docs will follow later..

- Implements failing test
- Implemented handling for the case where the router tree does not match up with the segment path being navigated to. This is what caused the underlying error.

This PR ensures that for the app directory, `beforeInteractive`, `afterInteractive` and `lazyOnload` scripts via `next/script` are properly supported.
For both `beforeInteractive` and `afterInteractive` scripts, a preload link tag needs to be injected by Float. For `beforeInteractive` scripts and Next.js' polyfills, they need to be manually executed in order before starting the Next.js' runtime, without blocking the downloading of HTML and other scripts.
This PR doesn't include the `worker` type of scripts yet.
Note: in this PR I changed the inlined flight data `__next_s` to `__next_f`, and use `__next_s` for scripts data, because I can't find a better name for `next/script` that is also short at the same time.

Kudos @dferber90 who found this issue. Added a test and handled it gracefully for now. Keep in mind the behavior can't be 1-1 so it takes the `as` as the `href` value given that masking of parameters in this way is no longer supported, that will be superseded by parallel routes / route interception.

Move react-dev-overlay into hot reloader client components, and let it imported by app router. So then we don't need to have hot reloader and react tree as adjacent sibilings but the overlay with error boundary is wrapping the react tree

Since `next/dynamic` has client hooks that not compatible with server
components, and app renderer doesn't provide context (such as
`LoadableContext`) for it to use. Previously we provided a simple
replacement using `React.lazy` for `next/dynamic` if you want to use it
in appDir.
This PR always alias it to the `React.lazy ` implementation for appDir
so that user won't need to worry about the dynamic options. They can
only use `dynamic()` without 2nd options arg
```js
import dynamic from 'next/dynamic'
const Dynamic = dynamic(() => import('./dynamic-component'))
```
- Add a failing test for navigating between many levels of dynamic routes
- Create router tree during prefetch action so that it can be reused across multiple urls
- Ensure segmentPath is correct when rendering a subtree. Previously it would generate a segmentPath that starts at the level it renders at which causes the layout-router fetchServerResponse to inject `refetch` at the wrong level.
- Fixed a case where Segment was compared using `===` which is no longer valid as dynamic parameters are expressed as arrays. Used `matchSegment` helper instead.

This commit implements the main proposal presented in
https://github.com/vercel/next.js/issues/39241
to add attribution to web vitals.
Attribution adds more specific debugging info to web vitals,
for example in the case of Cumulative Layout Shift (CLS),
we might want to know
> What's the first element that shifted when the single largest layout shift occurred?
on in the case of Largest Contentful Paint (LCP),
> What's the element corresponding to the LCP for the page?
> If it is an image, what's the URL of the image resource?
Attribution is *disabled* by default because it could potentially
generate a lot data and overwhelm the RUM backend.
It is enabled *per metric* (LCP, FCP, CLS, etc)
As part of this change, `web-vitals` has been upgraded to v3.0.0
This version contains minor bug fixes, please see changelog at

This caused unexpected full page reloads when viewing pages in `pages`. E.g. when navigating to `app`. Since `app` is the only place you can have server components now this is no longer needed.

Adds support for generating a fallback font by providing font override
metrics for the given local font. Also adds support for providing a CSS
variable name that then can be accessed through the `.variable` export,
it contains the hashed font family name.

Since React 18 returning `undefined` from components is allowed which renders to `undefined` in the RSC response so we need a separate prop to know if the loading boundary was provided.

Currently, a developer building a website using Next.js could write this
code with no type errors:
```tsx
<Image
width="kangaroo"
height="100px"
quality="medium"
{...rest}
/>
```
This PR adds stricter type checking, which will catch this type of error
earlier.
Similarly, this PR adds stricter types for the `responseLimit`, to
ensure the types align to:

This updates to ensure we properly error during static generation when a
non-dynamic SSR error is thrown so that unexpected errors are not
tolerated. This also fixes the static generation async storage not being
shared correctly due to different instances being created during
bundling.
This PR changes the external module resolution to eagerly bundle
node_modules, and some specific Next.js internal modules, if on the
`WEBPACK_LAYERS.server` layer. While resolving corresponding packages,
we use the `react-server` export condition (fallbacks to default).
A follow-up PR will be adding a Next.js option to opt-out specific
packages from being bundled on the server layer.

Leverages `AsyncLocalStorage` when available for handling static generation context and falls back to requiring render to be isolated when `AsyncLocalStorage` is not available.
Note: most changes are spacing so toggling to ignore spacing may make reviewing easier
