Doesn't resolve the root issue of why `_devPagesManifest.json` might fail to load. But does improve the log for when it happens. I'd suggest applying this same fix to `_devMiddlewareManifest.json` too.

Fixes: #38232
Fixes: https://github.com/vercel/next.js/issues/36893
Version [12.1.1-canary.5](https://github.com/vercel/next.js/releases/tag/v12.1.1-canary.5) introduced a bug, more specifically this PR: https://github.com/vercel/next.js/pull/34836
The issue described in #38232 is that the following code starts both the dev and prod servers:
```js
const start = require('next/dist/cli/next-start')
start.nextStart()
```
I searched a bit and found that `lib/get-project-dir.ts#getProjectDir()` now imports `bin/next.ts`
6b8e499c7b/packages/next/lib/get-project-dir.ts (L3)
and it calls a CLI command via
6b8e499c7b/packages/next/bin/next.ts (L137)
This `command` should not be defined, but it fallbacks to `defaultCommand`, which is `dev` (that explains why the dev server is also started)
This PR moves the `cliCommand` types and `commands` variable to a new separate file instead of `bin/next.ts`, to avoid running a CLI command when we import any file that also imports `lib/get-project-dir.ts`
Not sure how integration tests can be added for this issue, but feel free to tell me.

The 'with-static-export' example is very useful but, if a developer wants to use TypeScript, converting it is nontrivial. There are some gotchas in the GetStaticProps/GetStaticPaths functions. This example should help jumpstart TS development for sites static generation.

## Bug
When using next/server in different environment ([vitest](https://vitest.dev/)), named import will have runtime error.
```tsx
import { NextRequest } from 'next/server'
// TypeError: NextRequest is not a constructor
const request = new NextRequest()
```
This is conflicted with current `server.d.ts` files.
## Alternative
* reverte current `server.js` to esm, them compiled it to cjs.
Upgrade the README to use Docker Compose v2, which is faster and shipped by default with Docker Desktop since April.

In many browsers (other than Chrome), the `alt` text is visible while the image is loading. This causes a sense layout shift since you'll see a flash of text and then the image (although lighthouse measures 0 CLS, likely because Chrome doesn't have this problem). This PR updates `next/future/image` to hide the alt text, unless there is an error while loading the image in which case the `alt` text because relevant as the fallback.
Example:
<img width="115" alt="image" src="https://user-images.githubusercontent.com/229881/183128008-0660c50c-18aa-4e64-872e-ada9a652130f.png">
Unfortunately, Safari also shows a border while lazy loading images and it cannot be styled.
See upstream issue here: https://bugs.webkit.org/show_bug.cgi?id=243601
We were resizing animated images when importing them, but we don't optimize images when they come from an upstream provider. For consistency, we can skip resizing for local animated images as well.

Hi,
- Remove inlined CSS style which have minor performance loss. And hoist it to top of the component.
> Each time you inline an object, React re-creates a new reference to this object on every render. This causes components that receive this object to treat it as a referentially different one which have some performance pitfalls.
_Extremely sorry if I made any mistakes :(_

This PR removes the default styling of `object-fit:"contain"` for images using the future image component. This means images will get the default `object-fit` behavior of `"fill"`.
The main reason for this change is that an inline style will take precedence over external CSS, making this default behavior difficult to override with some styling strategies.

Currently next.js polyfills a [subset](https://github.com/vercel/next.js/blob/canary/packages/next-polyfill-nomodule/src/index.js) of APIs for `nomodule` browsers (such as IE 11), however it's not immediately clear to developers which APIs are transparently polyfilled.
For example, currently `Object.entries` is polyfilled and thus is usable in IE 11, but [it was decided](https://github.com/vercel/next.js/pull/15772#discussion_r463984612) that `Object.fromEntries` should not be polyfilled. As a developer, this is a confusing situation until you end up finding the `next-polyfill-nomodule` list of polyfills that are included.
This PR attempts to improve the Supported Browser Features page by:
- linking to the list of polyfills
- clarifying that custom polyfills are required for IE11 (and other old browser) compatibility
- moving the section on Sever-Side polyfills further down the page so all browser polyfill sections are better grouped together

Use flush effects to custom apply css-in-js solution to app. Re-introduce flush effects to app-render, and remove default support of styled-jsx in `app/`. So that users will choose their own css-in-js solution if they need any customization. styled-jsx won't appear in client bundle if you didn't use it.
For now we have to inject the initial styles before `</head>` to avoid hydration errors. Later on we can remove this once react can handle it.
- [x] inject styles before end of head element
- [x] add tests
