Ref: #33897
I took a naive approach and simply added `.env` to the files that need to be copied.
Do we want to include `.env.production` as well? Ref: https://nextjs.org/docs/basic-features/environment-variables#loading-environment-variables
(I haven't tested what happens if the file does not exist on copy.)
Other files like `.env.*local` or `.env.{test,development}` don't make sense to copy.

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.

* should fix#33043.
it should not leak into the client runtime

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.

Item 1 is the preparation for middleware-ssr-loader. Then we can do the following there

result.pipe(renderResult)

When using the web runtime with SSR streaming, this PR significantly improves the build speed for large applications when there're large modules shared by most pages.
With another optimization, `react-dom` will now be excluded in the web runtime build if it's imported in the application. It will only take effect in the client bundle.

This fix the custom 404 is not rendering properly and can’t be built in web runtime when `concurrentFeatures` is enabled. We force 404 page to be rendered outside of middleware ssr. Then it could be the real fallback 404 page in next-server when any routes is not macthed.
Will check 500 related after #31057 is landed.

With this PR we are updating the way we check the usage of `eval` and other dynamic code evaluation (like `new Function`) for middleware. Now instead of simply showing a warning it will behave differently depending on if we are building or in development.
- Development: we replace the dynamic code with a wrapper so that we print a warning only when the code is used. We don't fail in this scenario as it is possible that once the application is built the code that uses `eval` is left out.
- Build: we detect with tree shaking if the code that will be bundled into the middleware includes any dynamic code and in such scenario we make the build fail as don't want to allow it for the production environment.
Closes#30674

This re-enables minifying middleware chunks as testing on nextjs.org and front shows it is working properly now. The separation of middleware chunks from other client chunks is still kept in this PR to ensure client code doesn't leak into middleware bundles.

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.

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.
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.
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

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.
