### What?
Add configuration options to modify the `bodyParser` size as it used to
be available in Page Router.
### Why?
Server Actions "Error: Body exceeded 1mb limit" cannot be resolved since
the body-parser limit size is hardcoded to `1mb`.
### How?
Closes NEXT-
Fixes #

### What?
Add configuration options to modify the `bodyParser` size as it used to
be available in Page Router for APIs.
```js
export const config = {
api: {
responseLimit: false | '8mb'
},
}
```
Reference: [API Routes Response Size
Limit](https://nextjs.org/docs/messages/api-routes-response-size-limit)
### Why?
Server Actions "Error: Body exceeded 1mb limit" cannot be resolved since
the body-parser limit size is hardcoded to `1mb`.
```js
// /packages/next/src/server/app-render/action-handler.ts
// ...
const actionData = (await parseBody(req, '1mb')) || ''
// ...
```
Reference:
https://github.com/vercel/next.js/blob/canary/packages/next/src/server/app-render/action-handler.ts#L355
### How?
- Added option "serverActionsLimit" as `SizeLimit` type to
`config-shared.ts`
- Modified `action-handler.ts` to validate `serverActions` &
`serverActionsLimit` options in nextConfig
- Added conditional `serverActionsLimit` value and `1mb` if falsy
**Working on testing**

This PR addresses a problem where the `createServerReference` is using
the default condition of flight client (gets resolved to the Node
build), but we use the Edge build of flight client for SSR. This causes
2 flight clients to exist during SSR.
### What?
Update docs for Google Analytics 4
### Why?
This page doesn't make it clear which script is recommended, and has code that's outdated and erroring.
### How?
Update headings and clean up bad code.
This removes calls for rendering files in `pages/` via the server code and relies instead relies on the bundled `routeModule` to perform the rendering.
Future cases that try to call the legacy render will hit a new:
```
Invariant: render should have used routeModule
```
Error. These cases should be reported.
## What?
Adds a default modularizeImports that ensures `lucide-react`, `@mui/icons-material`, `lodash`, and `react-bootstrap` do not cause a massive amount of modules to be compiled in development.
For example `@mui/icons-material` re-exports 10600 (10K+) modules from a single file. Even though it does not affect production bundle size it does affect build time, especially in development, and even more so when your filesystem is slow (e.g. what we're seeing on Windows).

Due to the size of grid tracks specified in the CSS I amended the usage of the HTML `sizes` attribute.
The media can be ascertained from `gridTemplateColumns` and `gridGap` values, this change results in smaller images also being available in the srcset for use with sizes, which should be more performant.
### What?
Adds `supabase-js` as dependency for `with-supabase` example
### Why?
`with-supabase` example is missing `supabase-js` dependency, which is a
peer dependency of `@supabase/auth-helpers-nextjs`
### How?
Adds `supabase-js` to `examples/with-supabase/package.json`

Request data flow in the server
```
request ---> router worker (1) ---> ipc ---> render worker app (2)
|-----> render worker pages (3)
```
When it's hitting `_next/*` unmatched routes in standalone server, it will render 404, but when you hit `_next/*` it will render app not-found as the app router is always enabled, but router worker isn't set up with require-hook for proper built-in react version, then the app-render will fail with `./server.edge` exports not found error.
We detect if it's in the render worker, then do the app paths rendering instead of directly looking up for app paths in route worker. This could avoid unexpected accesses to the app-render

fix NEXT-1260
When conflicted pages occur between app and pages server used to throw error and you need to solve the conflicts and restart the server.
This PR capture the error during files aggregation, and send to client to display the error for files confliction. This will send all the conflicts to client and it will still error until you solve all of them. But since the server is not stuck by errors, client can recover once the error is solved.
Closes NEXT-1283
The next-metadata-route-loader emitted content with `"next/server"` is still using cjs version which is not get tree-shaked on edge runtime, This PR adds a new esm entry for it and mapped it that on edge runtime so unused exports can be tree-shaked. This case happened when users are using ImageResponse from `"@vercel/og"` instead of `"next/server"`.
2nd change is adding another alias to map `@vercel/og` package to vendored og package inside next.js, this way we could merge the two package instead of bundled both of them
Fixes: NEXT-1303
changed `require.reoslve("next/dist/xxx")` to `${NEXT_PROJECT_ROOT}/xxx}` to avoid to be traced by nft.
### What?
Adds missing "DO NOT EDIT" comment to some of the shared documentation pages"
### Why?
A few of the shared documentation files didn't have the comment to not edit them.
Continuing on changes to move the rendering logic into the bundles.
- Unifies edge render functions: `appRenderToHTML` and `pagesRenderToHTML` becomes `renderToHTML`
- When an error occurs, the error module's match is used so the module's internal render can be used (easing transition away from using the server's render method)
- Improved test resiliance
Tailwind CSS configuration is missing in the docs when configuring the `src` folder

### What?
Paths with interception markers adjacent to dynamic segments are not correctly parsed, which leads to the path match logic failing.
### Why?
`getParametrizedRoutes` checks for brackets but isn't expecting to receive an interception marker. For example, a path of `/photos/(.)[author]/[id]` results in the following regex:
`/^\/photos\/\(\.\)\[author\]\/([^/]+?)(?:\/)?$/`
This will not match a path of `/photos/(.)zack/1` since it retained the `[author]` brackets.
`getSegmentParam` has a similar issue when getting values for path params, though we can just skip the interception markers and go straight to the params.
Closes NEXT-1166, NEXT-1013

### What?
This is an alternative to #51330, which only support aborting the response (doesn't support back-pressure). If the client cancels the request (HMR update, navigates to another page, etc), we'll be able to detect that and stop pulling data from the dev's `ReadableStream` response.
### Why?
We want to allow API routes to stream data coming from another server (eg, AI services). The responses from these other servers can be long running and expensive. In the case the browser aborts the connection, it's critical that we stop streaming data as soon as possible.
### How?
By checking whether `response.closed` is set during the `for await (…)` iteration, we're able to detect that the client has aborted the connection. Cleanup of the `ReadableStream` is handled implicitly by the async iterator when the loop ends.
The one catch is our use of http-proxy for worker processes. It does not properly detect a client disconnecting (but does handle back-pressure). In order to fix that, I've manually added event listeners to detect the disconnect and cancel the proxied req/res pair.

### What?
Currently, when the check on validating the type of `revalidate` is run,
we use the `Number` function to parse the value of `revalidate`, however
the `Number` function takes a
[`StringNumericLiteral`](https://tc39.es/ecma262/2023/#prod-StringNumericLiteral)
which doesn't allow the usage of the `_` separator to format your
numbers. This PR allows you to add numeric separators in the
`revalidate` export.
### Why?
When configuring the actual code, we should be allowed to use numeric
separators as it is a syntax that is supported by most runtimes.
### How?
A simple `replaceAll` call that removes all `_`s between digits.

Small QOL improvements to `RenderResult` and `RouteModule` setup. This
also adds a test to verify that headers aren't sent on responses that
have already been sent.
