This change allows disabling automatic `npm install`(or other supported
package managers).
Installing NextJS dependencies takes a long time and results in 0.5GB on
disk inside `node_modules`, it's not always what you want as sometimes
it's useful to delay dependency installation to a later time.

### What?
This PR fixes OpenGraph generation code with local assets in Node.js
runtime. Also adds some notes on file location.
The updated code is validated with my project on vercel.
### Why?
I tried loading a file in `public` folder(say `./public/og.png`). The
Node.js local assets example code did work locally with `next start` but
failed with error message `Error: ENOENT: no such file or directory`
when deployed to vercel.
Then I found out the trick here is the relative path. On my local
machine the CWD is the root folder so the relative path works, And it
seems the CWD is somewhat different on vercel runtime. Then I tried
using `process.cwd()` to get the CWD and construct a absolute path, this
has been validated with my project on vercel.
Also it's worthy to note where the local assets should be placed, so
that devs could be less confused.

### What
Closes PACK-2978, requires https://github.com/vercel/turbo/pull/8005.
PR extends existing mdxRs config from accepting object as well in
addition to current boolean flag, mainly to allow to specify what kind
of markdown types will be used between gfm and commonmark.
The `params` example in the docs for `default.js` have the slot/params
in the wrong order, giving the impression that you can deeply nest
`default` slots.
This clarifies that the params received by a slot are based on the
dynamic params leading up to the segment containing the slot.
Fixes#64708
Closes NEXT-3160
The `@appsignal/nodejs` instrumentation package fails to load in Next.js
14 due to Webpack failing to bundle its Node.js native extension. Adding
it to the server components external packages list fixes this issue.
Part of https://github.com/appsignal/appsignal-nodejs/issues/1014.
### What?
Adds a Node.js example for using assets with `ImageResponse` to create
og images.
### Why?
The only examples available use `new URL` and `fetch` which does not
work when the runtime is using Node.js.

Clarify best practices for implementing authentication in Next.js,
including what Next.js and React features to use and when. With the
minimum number of tools, we'll try to teach authentication from first
principles (simple password + email), then recommend Next.js-compatible
libraries, and further resources.
**Authentication:**
- [x] Forms and Server Actions
- [x] Server-side form validation and early returns
- [x] Form errors with `useFormStatus()`
- [x] Pending states with `useFormState()`
**Session Management:**
- [x] Stateless Sessions
- [x] Database Sessions
- [x] Setting cookies on the server
- [x] `cookies()`
- [x] `sever-only`
**Authorization:**
- [x] Optimistic vs. secure checks
- [x] Middleware for optimistic checks
- [x] Performance caveats - what not to do
- [x] DAL - centralizing data requests, verifying auth state close to
the data source
- [x] `redirect()`
- [x] DTO - returning the minimum data, preventing exposure on the
client
- [x] Recommendations for:
- [x] Server Components
- [x] Partial rendering and `layout` caveats
- [x] Server Actions
- [x] Route Handlers

authentication?"](https://www.notion.so/vercel/00b2a5121a264939a5d4d10f76b36954?v=cac009672f9d411f900f41a0c3971702&p=2a80e8d450f54ea58da5cf8b42c15ac1&pm=s).

### 🤔 What's in there?
We've deprecated config's `analyticsId` in 14.1.1 [almost 3 months
ago](https://github.com/vercel/next.js/releases/tag/v14.1.1-canary.2).
Users can opt in fot `@vercel/speed-insights`, or use
`useReportWebVitals` to report to any provider they'd like.
This PR:
- removes `analyticsId` key from configuration
- stops setting `__NEXT_PUBLIC_ANALYTICS_ID` env variable when the key
was present
- stops injecting `performance-relayer` file, when the variable is set
- cleans up related test code.
`fetchCache` is a more fine-grained segment level cache-control
configuration that most people shouldn't have to use. Current semantics
of `dynamic = "force-dynamic"` will still treat the fetch as cacheable
unless explicitly overriding it in the fetch, or setting a segment level
`fetchCache`.
The `dynamic` cache configuration should be seen as a "top-level"
configuration, while more fine-grained controls should inherit logical
defaults from the top-level. Otherwise this forces people to opt-into
the `fetchCache` configuration, or manually override each `fetch` call,
which isn't what you'd expect when forcing a segment to be dynamic.
This will default to not attempting to cache the fetch when
`force-dynamic` is used. As a result, I had to update one of the
`app-static` tests to use `revalidate: 0` rather than `force-dynamic`,
as the revalidate behavior is slightly different in that it won't modify
the revalidation time on a fetch if it's non-zero.
Closes NEXT-2067
## Why?
When you do, →
```
const router = useRouter()
console.log('[test] router =', router.query.slug)
```
the value of `router.query.slug` should be undefined in this instance.
(screenshot from current docs)
it should be `slug: undefined`.
### Improving Documentation
mistake in the docs.
action should not be apply on the button.
only formAction or onClick is allow.

Provides a `revalidateReason` argument to `getStaticProps` ("stale" |
"on-demand" | "build").
- Build indicates it was run at build time
- On-demand indicates it was run as a side effect of [on-demand
revalidation](https://nextjs.org/docs/pages/building-your-application/data-fetching/incremental-static-regeneration#on-demand-revalidation)
- Stale indicates the resource was considered stale (either due to being
in dev mode, or an expired revalidate period)
This will allow changing behavior based on the context in which it's
called.
Closes NEXT-1900
