This adds handling for prefetching `onTouchStart` as this gives a little more time to start parsing required scripts for a page transition if not already done that can help make the transition faster. This is based on research showing the touch start event firing on average `90ms` before click (x-ref: [source](https://instant.page/#:~:text=in%20the%20world.-,On%20mobile,-A%20user%20starts))
This also adds testing safari with playwright so we can run these in PRs instead of only after merge and adds initial mobile testing as well.

Lands #37431 again, but it only solves the re-render issue completely for the middleware case (closes#38267), not the `rewrites` case (#37139).
For `rewrites`, the blocker is `isReady` always being `false` initially and to match the markup on hydration we can't simply work around it without a re-render. Need to come up with another fix.

The PR implements the details about un-extractable fields in the `UnsupportedValueError`.
The PR also enhances the warning message about the unrecognizable `config` field. Now the warning message will look like this:
```
warn - Next.js can't recognize the exported `config` field in route "/unsupported-value-type":
Unsupported node type "CallExpression" at "config.runtime".
The default config will be used instead.
Read More - https://nextjs.org/docs/messages/invalid-page-config
```
The corresponding production test case has also been updated.
This line was introduced in #38862 to the base server but should only be useful for the Node.js server:
```js
addRequestMeta(req, '__NEXT_CLONABLE_BODY', getClonableBody(req.body))
```
It also introduces polyfill of `stream` to the edge server.
Here we add an abstract method to handle it differently, where only `__NEXT_INIT_QUERY` is used.

Fixes#38743.
Fixes: https://github.com/vercel/next.js/pull/38750
The PR adds basic `TemplateLiteral` support for static analysis.
The corresponding re-production of #38743 has also been implemented in e2e tests.
This ensures we correctly detect query and hash values when there are `?` characters in the hash. A regression test to ensure this working properly has been added.

Fixes: https://github.com/vercel/next.js/issues/38783
This PR updates the Edge Runtime to use a new version that loads dependencies differently. This addresses https://github.com/vercel/next.js/pull/38766 so `instanceof` works as expected.
It involved a few code changes, mostly regarding to types. The most important change is that the `Runner` function in the sandbox doesn't take a `ReadableStream` as `body` anymore since this implies creating the instance on "node land" and makes the runtime `fetch` function not to be able to compare with `ReadableStream` using `instanceof`. Instead we introduce a "clonable body" abstraction that allows to create the `ReadableStream` from `Readable` by using the edge runtime primitive which would hold the correct prototype.
Also, this PR changes the way we pre-compile the Edge Runtime to adapt it to the new version.
`experimental.optimizeCss` from `next.config.js` can be an object containing the critters' option:
70a53e0789/packages/next/server/post-process.ts (L224-L232)
The PR corrects the ajv schema and the type definition of `experimental.optimizeCss`.
## What’s in there?
This PR brings more consistency in how errors and warnings are reported when running code in the Edge Runtime:
- Dynamic code evaluation (`eval()`, `new Function()`, `WebAssembly.instantiate()`, `WebAssembly.compile()`…)
- Usage of Node.js global APIs (`BroadcastChannel`, `Buffer`, `TextDecoderStream`, `setImmediate()`...)
- Usage of Node.js modules (`fs`, `path`, `child_process`…)
The new error messages should mention *Edge Runtime* instead of *Middleware*, so they are valid in both cases.
It also fixes a bug where the process polyfill would issue a warning for `process.cwd` (which is `undefined` but legit). Now, one has to invoke the function `process.cwd()` to trigger the error.
It finally fixes the react-dev-overlay, where links from middleware and Edge API route files could not be opened because of the `(middleware)/` prefix in their name.
About the later, please note that we can’t easily remove the prefix or change it for Edge API routes. It comes from the Webpack layer, which is the same for both. We may consider renaming it to *edge* instead in the future.
## How to test?
These changes are almost fully covered with tests:
```bash
pnpm testheadless --testPathPattern runtime-dynamic
pnpm testheadless --testPathPattern runtime-with-node
pnpm testheadless --testPathPattern runtime-module
pnpm testheadless --testPathPattern middleware-dev-errors
```
To try them out manually, you can write a middleware and Edge route files like these:
```jsx
// middleware.js
import { NextResponse } from 'next/server'
import { basename } from 'path'
export default async function middleware() {
eval('2+2')
setImmediate(() => {})
basename()
return NextResponse.next()
}
export const config = { matcher: '/' }
```
```jsx
// pages/api/route.js
import { basename } from 'path'
export default async function handle() {
eval('2+2')
setImmediate(() => {})
basename()
return Response.json({ ok: true })
}
export const config = { runtime: 'experimental-edge' }
```
The expected behaviours are:
- [x] dev, middleware/edge route is using a node.js module: error at runtime (logs + read-dev-overlay):
```bash
error - (middleware)/pages/api/route.js (1:0) @ Object.handle [as handler]
error - The edge runtime does not support Node.js 'path' module.

## Notes to reviewers
Edge-related errors are either issued from `next/server/web/sandbox/context.ts` file (runtime errors) or from `next/build/webpack/plugins/middleware-plugin.ts` (webpack compilation).
The previous implementation (I’m pleading guilty here) was way too verbose: some errors (Node.js global APIs like using `process.cwd()`) could be reported several times, and the previous mechanism to dedupe them (in middleware-plugin) wasn’t really effective.
Changes in tests are due to renaming existing tests such as `test/integration/middleware-with-node.js-apis` into `test/integration/edge-runtime-with-node.js-apis`. I extended them to cover Edge API route.
@hanneslund I’ve pushed the improvement you did in https://github.com/vercel/next.js/pull/38289/ one step further to avoid duplication.
Fixes a bug where `import { nanoid } from 'nanoid'` broke the tests.

Drop the `next/streaming` endpoint. Currently it only holds the only one experimental api and we'd like to deprecate it in favor of oher future APIs for app dir
Currently, when a user forgets the `src` prop on an image, an error is thrown. However that error doesn't include any of the the user's code in the stack trace, so its nearly impossible to figure out which image is the culprit if there are multiple images on the page.
Since this error only throws on demand when a page is visited during `next dev`, we can instead delay the error so it no longer prints on the server but prints on mount instead. At that point, we'll have the `<img>` element via ref and can print it to the web console with the stack trace.

I noticed our internal comments about exported functions that should not be used in application code.
TSDoc has the [`@internal`](https://tsdoc.org/pages/tags/internal/) option that can be used together with TS's [`stripInternal: true` compiler option](https://www.typescriptlang.org/tsconfig/#stripInternal), hiding these from inferred types:
Before:
After:
It would also be great to use `/**/` comments instead of `//` when documenting methods/properties/functions, as these can be picked up by the editor when referring to these, so someone new to the codebase will hopefully have to jump around less to get some useful comments.

Starting in Node.js 18, the `fetch` global was made available and that caused the squoosh implementation to assume it was on a web browser and try to fetch the wasm file instead of reading it from the filesystem. This PR deletes the code trying to fetch since we know that squoosh only runs in the Image Optimization API, not the browser.
- Fixes#38020
- Enables a test that was disabled in #38460
## How to reproduce
1. create a next.js app with a middleware (or an edge route) that imports a node.js module:
```js
// middleware.js
import { NextResponse } from 'next/server'
import { basename } from 'path'
export default async function middleware() {
basename()
return NextResponse.next()
}
```
2. deploy it to vercel with `vc`
3. go to the your function logs in Vercel Front (https://vercel.com/$user/$project/$deployment/functions)
4. in another tab, query your application
> it results in a 500 page:
<img width="517" alt="image" src="https://user-images.githubusercontent.com/186268/179557102-72568ca9-bcfd-49e2-9b9c-c51c3064f2d7.png">
> in the logs you should see:
<img width="1220" alt="image" src="https://user-images.githubusercontent.com/186268/179557266-498f3290-b7df-46ac-8816-7bb396821245.png">
## Expected behavior
The route should fail indeed in a 500, because Edge runtime **does not support node.js modules**. However the error in logs should be completely different:
```shell
error - Error: The edge runtime does not support Node.js 'path' module.
Learn More: https://nextjs.org/docs/messages/node-module-in-edge-runtime
```
## Notes to reviewers
I introduced this issue in #38234.
Prior to the PR above, the app would not even build, as we were checking imported node.js module during the build with AST analysis.
Since #38234, the app would build and should fail at runtime, with an appropriate error.
The mistake was to declare `__import_unsupported` function in the sandbox's context, that is only used in `next dev` and `next start`, but not shipped to Vercel platform.
By loading it inside webpack loaders (both middleware and edge route), we ensure it will be defined on Vercel as well.
The existing test suite (`pnpm testheadless --testPathPattern=runtime-module-error`) covers them.
Fixes#38533 by including `src/` as a default linting directory where all files within are linted
