As per React 18 recommendation, we should use e.g. `renderToReadableStream` whenever we use `createRoot`. This is particularly important for currently supported suspense features like `React.lazy` to work properly during SSR.
However, unless you have opted in to streaming support (via [the `runtime` flag](https://github.com/vercel/next.js/pull/34068)), we will wait until `onCompleteAll` before sending it (via the `generateStaticHTML` flag).

Fixes#33879
The `export default xxx` statement is slightly different from estree when exporting an arrow function instead of identifier in swc.
We also need to capture arrow exports.

Fixes: https://github.com/vercel/next.js/issues/30631
Cleans up the code of the middleware SSR loader and the web server. Currently the page components and render options are provided to the server via `globalThis` which is not ideal.
Instead we can inject `extendRenderOpts` and `loadComponent` to the web server. Since this is the the minimal mode and we'll need to handle `?flight` requests, we update the server render opts upon `updateRenderOpts` (In the future this should be changed to be passed to `requestHandler` to avoid race conditions).
Currently, we can't fully get rid of the `__server_context` global as we call `getBuildId` in the base server constructor.

In the web runtime, currently we use `absolute500Path || absoluteErrorPath` to act like `/_error`. This PR fixes the behavior to use the `/pages/500.js` for 500 errors and `/pages/_error.js` for 500 fallback and other errors.

(#31506 for context)
This PR implements the minimum viable web server on top of the Next.js base server, and integrates it into our middleware (edge) SSR runtime to handle all the requests.
This also addresses problems like missing dynamic routes support in our current handler.
Note that this is the initial implementation with the assumption that the web server is running under minimal mode. Also later we can refactor the `__server_context` environment to properly passing the context via the constructor or methods.
Part of #31506, this PR removes `loadEnvConfig` and `chalk` from the base server while keeping the same behavior for the node server.

Production middlewares will only expose env vars that are statically analyzable, as mentioned here: https://nextjs.org/docs/api-reference/next/server#how-do-i-access-environment-variables
This creates some incompatibility with `next dev` and `next start`, where all `process.env` data is shared and can lead to unexpected behavior in runtime.
This PR fixes it by limiting the data in `process.env` with the inferred env vars from the code usage. I believe the test speaks for itself 🕺

After discussing with @sokra, seems that the proposed solution is split in two:
* We need to make sure that the `process` polyfill uses `global.process` if available. This is because middlewares are bundled using `browser` target and therefore `process.env.MY_ENV` gets shimmed into `require('process').env.MY_ENV`.
* Allow `process.env` to be statically analyzed for dependencies so they will be exported to the manifest.

# Description
The redirect responses do not contain a message body. This is in conflict with the RFCs (below) and causes Traefik (a reverse proxy) to invalidate the responses. In this pull request, I add a response body to the redirect responses.
This PR is similar to https://github.com/vercel/next.js/pull/25257, it appears that there are some other locations where redirection is handled incorrectly in next.js.

This PR implements the basic inline embedded server response data (#30994) for RSC, as well as partial hydration (#31338) for RSC and React 18 SSR streaming.
For #30994, `renderTargetSuffix` is passed to the `bodyResult` resolver so the stream can inject corresponding hydration scripts and the closing body tag at the correct time. The expected behavior should be _prefix_, _body shell_, _suffix scripts_, _stream and inlined data_, _close body_.
For #31338, we have to force turn on `disableOptimizedLoading` when `concurrentFeatures` is enabled to opt-out of deferred script tags.

Since #31939 is going to move the `Document` components, we can't rely on `DefinePlugin` to provide environment variables. This PR passes them as render opts instead. We can't just force this to be bundled like e.g. `next/dynamic`, because we use it internally.
`isAutoExport` should be `false` when `concurrentFeatures` is enabled.

To run middleware we are using a **sandbox** that emulates the web runtime and keeps a module cache. This cache is shared for all of the modules that we run using the sandbox while there are some module-level APIs that must be scoped depending on the module we are running.
One example of this is `fetch` where we want to always inject a special header that indicate the module that is performing the fetch and use it to avoid getting into infinite loops for middleware. For those cases the cached implementation will be the first one that instantiates the module and therefore we can actually get into infinite loops. This is the reason why #31800 is failing.
With this PR we refactor the sandbox so that the module cache is scoped per module name. This means that one execution of a middleware will preserve its cache only for that module so that each execution will still have its own `fetch` implementation, fixing this issue. Also, with this refactor the code is more clear and we also provide an option to avoid using the cache.

Initial step to refactor the rendering logic by decoupling the handler and renderer:
1. Delegate Flight rendering to server/render
2. Reuse the piper glue code for both Fizz and Flight streams
3. Add buffering for ReadableStream
In 1), this PR also makes sure that gSSP/gSP are correctly executed before the Flight stream and `pageProps` and `router` are correctly delivered to the component.
