This will ensure an image hashed consistently regardless of how its imported:
- `import file from "./file.png"` -> /_next/static/media/file.12345678.png
- `url(./file.png)` -> /_next/static/media/file.12345678.png
- `new URL("./file.png", import.meta.url)` -> /_next/static/media/file.12345678.png
* Add experimental config for middleware

This skips minifying middleware as it can cause issues in some cases like the below error and also isn't necessary to be minified as we don't currently minify other server pages.
```
TypeError: (intermediate value)(intermediate value)(intermediate value)(...) is not a function

This PR adds support for [Middleware as per RFC ](https://github.com/vercel/next.js/discussions/29750).

This updates the `outputFileTracing` to fix a few cases we noticed where files weren't caught and also ensures we match webpack's `esm` resolving so that we don't include `cjs` files when webpack expects `esm`, it also updates to the latest `@vercel/nft` version which removes the caching in favor of ensuring the `reasons` map contains all parents allowing us to trace all entries in one `nodeFileTrace` run and the collect the separate files for each entry from the `reasons` map giving us much better performance/reliability.
This also ensures we don't include static image imports when enabled in the traces since they can drastically increase deployment size on larger projects.

These are all related to `swcLoader`:
- Fixes commonjs code being output as ESM
- Fixes bug with `getServerSideProps` not getting querystrings and added tests for it
- Disable SWC on Babel test suites
- Disable SWC on no-anon-default-export test suite
- Disable SWC on page-config test suite (pending porting of the Babel plugin)
- Ensure `sourcesContent` is part of the sourcemap

This fixes cases where not all `package.json`s were being added to the traces correctly while using webpack's resolving with the `outputFileTracing`. The specific case notice while testing has been added as an integration test to ensure it is working as expected.
Follow-up to https://github.com/vercel/next.js/pull/29473 after additional testing it seems we need to ensure the `main` field is used when tracing packages during builds so that `module` isn't being used unexpectedly.
Follow-up to https://github.com/vercel/next.js/pull/29307 this ensures the `blurDataURL` is correctly prefixed with the `basePath` in development since we use the `_next/image` endpoint to generate the placeholder in dev mode.

This updates to the latest version of `node-file-trace` and leverages the new async fs handling with webpack. In a follow-up PR we will implement the async resolver to share resolving with webpack as well.

Currently the span is finished on seal but that's not the actual timing where the entry span is finished as there's a `succeedEntry` hook. This PR changes the span to finish on `succeedEntry`.

Currently `new URL()` for server assets is completely broken because of the `publicPath` that is used for them too. `new URL()` for SSR is broken on windows as it's using absolute urls on the windows filesystem. And `new URL()` is using an incorrect filename
* Place all `asset`s correctly in `/_next/static/media` with `[name].[hash:8][ext]`
* Added a separate runtime chunk for api entries, without `publicPath`
* Introduce separate layer for api entries, which uses server-side URLs.
* Otherwise new URL() will return a faked relative URL, that is identical in SSR and CSR
* Disables react-refresh for api entries

We're no longer currently planning on supporting caching for dynamic responses, so we can do some cleaning & simplification:
* Multiplexing can be removed since we only ever subscribe once (via `RenderResult.pipe`, described below)
* `RenderResult.toUnchunkedString` can become synchronous since static responses are never chunked
* `RenderResult.forEach` can become `RenderResult.pipe` which helps encapsulate some of the details of `RenderResult`
* Expose minify in next-swc
* Expose minify in js binding
* Use new minify function in terser plugin
* Only upload changed binary artifact
* Build next-swc binaries
* Add swc license info to copied file
This is a follow-up to https://github.com/vercel/next.js/pull/28227 to ensure `_app` and `_document` HMR correctly when you start the dev server and then add `_app` and `_document`.

Our `Observable` use has gotten sufficiently complex that it makes sense to just use a 3rd party implementation and not worry about maintaining it ourselves. As a bonus, it doesn't rely on Node APIs.
Add `-js` `-ts` `-tsx` `-css` to `build-module` in traces to allow for easier filtering.

Removes the extra webpack handling that was previously done, this ensures the file which is already minified and compiled does not get passed through minification again.

The polyfill loading already has tests so no other changes are necessary.

Adds `RenderResult`, replacing the `string` that `renderToHTML` used to return, with an `Observable`-like API that callers can use to subscribe and get a callback when chunks are available to flush, etc.
This is the last architectural change needed for streaming. There are, however, other things currently standing in the way of streaming. For example, it is common to mutate `res` in `getServerSideProps` to do routing work, or write headers, before fetching page data. This pattern effectively nullifies any advantages of streaming. I may do a follow-up PR that adds an experimental alternative for applications not using React 18, but the main purpose for this support is for Suspense and Server Components.
For that reason, there's no actual streaming here yet: instead we just flush a single chunk. A follow-up PR will add support for streaming suspense boundaries in React 18.

Currently there is a lot of mutation in the Next.js Server and the checks for Locale are directly coded in the general request handler. Ideally, we should have a function where we just pass the request input (url + headers + config) and generate a bunch of metadata that analyzes it generating all metadata we might require for both the URL and i18n + basePath information.
This PR brings:
- A new parsing function `parseUrl` that joins parsing an absolute/relative URL into a data structure compatible with the Node parsing output but missing redundant properties.
- A wrapper `parseNextURL` that extends `parseUrl` analyzing `i18n` and `basePath` based on the provided configuration, url and headers. This function is pure and stateless so it can be used outside of the Next.js context.
- Types improvements and reuse.
- Refactors `next-server.ts` request handling using the above mentioned functions so that the code there just apply effects to the `req` object and the `parsedUrl.query` leaving the code much more straightforward.
- Refactors `getRouteRegex` decomposing in two different functions where `getParametrizedRoute` can be used to retrieve the serializable data that is used to generate the Regex.
when typechecking next.config.js as described [in the docs](https://github.com/vercel/next.js/blob/canary/docs/basic-features/typescript.md#type-checking-nextconfigjs), an error would be thrown if `future` and `experimental` are missing. When using `Partial<>` in the type definition instead, it works as expected.

This PR changes the implementation of `placeholder=blur` when using `next dev` so that it lazy loads on-demand.
This will improve the developer experience for web apps with many blurred images.

pure cjs package: CommonJs package that prevents importing via `exports` field when `import` is used.
`*` This case will behave a bit unexpected for now, since `require` will return a Promise. So that need to be awaited. This will be fixed once the whole next.js bundle is ESM. It didn't work at all before this PR.
`**` This is a new Error when trying to require an esm package.
`***` For mixed packages we prefer the CommonJS variant to avoid a breaking change.

fixes#26607
This change makes it so the image loader plugin only emits a file while processing an image import for the client. The final generated image URL was already the same in SSR and CSR anyway, so this change doesn't have any functional impact.
I also changed the name of the static page in the image component tests, since it was causing some conflicts with the static assets folder.
