### What?
I'm recreating a PR because CI of
https://github.com/vercel/next.js/pull/58712 uses `lightningcss@1.14.0`
for an unknown reason.
Add an opt-in feature to use `lightningcss` instead of webpack
css-loader.
### Why?
In the name of performance.
### How?
This PR is largely based on https://github.com/fz6m/lightningcss-loader
by @fz6m.
(Thank you for nice work)
Closes PACK-1998
Closes PACK-2124

### What?
* upgrades turbopack for `getResolve` in webpack loaders
* add missing resolve-url-loader to turbopack for full sass support
Closes PACK-2634
## Description
Refactor the [Next.js
CLI](https://nextjs.org/docs/app/api-reference/next-cli) to use
[commander](https://github.com/tj/commander.js) instead of
[arg](https://github.com/vercel/arg).
## Why?
- Auto-generated, properly formatted help command + output. With `arg`,
much of the help commands were manually added via a single
`console.log`, causing deviations over time.
- Ergonomic, ease of adding new subcommands and rules
## Breaking Changes
- Update the experimental `next experimental-compile` and `next
experimental-generate` build commands in favor of `next build
--experimental-build-mode=compile/generate`

## What?
Migrates the Sass support tests from `test/integration` (legacy test
suite) to `test/e2e`, this way all these tests run against both
development and production, whereas previously most of them would only
run against production.
This is helpful as it ensures the tests are running against Turbopack
too, which is highlighting some missing features in Sass support for
Turbopack.
I've had to rewrite most of the tests to check against the actual
rendered output in the browser instead of CSS output in the `.next`
folder, the majority of these now run regardless of implementation
details.

This ensures our dynamic routes that have the same specificity as
`_next/static/:path*` don't get matched unexpectedly when the
`_next/static` asset doesn't exist. We were holding off on making this
change explicit due to compatibility concerns but these are no longer a
concern and the unexpected matching is more of a concern.

## What?
Groups together the scss tests. I'm working on refactoring these to use
`test/e2e` instead as many tests currently only run during builds and we
want to make sure these Sass tests run for Turbopack (which is dev only
currently) to catch bugs.

### What?
The [create-next-app
documentation](https://nextjs.org/docs/app/api-reference/create-next-app#non-interactive)
under API reference says that;
> Further, you can negate default options by prefixing them with --no-
(e.g., --no-eslint).
When I tried to use --no-import-alias, I thought that it would
automatically use the default alias (@/*), but it does not.
### Why?
Each option has --no prefix control but import-alias has no --no prefix
control to give default value to program.
In an [Interactive](https://nextjs.org/#interactive) approach, the user
can select a prompt; `Would you like to customize the default import
alias (@/*)? No / Yes.` If the user selects no, then the default alias
is applied with @/*.
### How?
Implementing a condition solve the problem for general purpose. If
arguments includes `--no-import-alias` then the importAlias section
automatically apply the default value.

This ensures we don't normalize the `distDir` in the webpack config in
dev mode as it won't be moved to the right location like it is during
build.
Fixes: https://github.com/vercel/next.js/issues/61105
Closes NEXT-2495
### Why?
I really dislike the way `.chain` works right now, it shouldn't mutate
the `BrowserInterface`, this PR changes it so it's just a pure chain
without weird side effects.
One example with the current version (before this PR):
```
const el = browser.elementByCss('#version-2')
await el.text()
// throws
await el.text()
```
### Additional Changes
- removes selenium (which is completely unused)
- updates playwright
- makes the playwright tracing not error all the time
Previously, this error was confusing because it made it sound like the
`sizes` prop was missing. This was because the default value of `sizes`
is `100vw` so the previous code couldn't tell the different between
implicit vs explicit `100vw`.
This PR changes the code to read the input value from the `sizes` prop
and prints a better warning.
Fixes NEXT-2441
To ensure that we properly cache data for routes that change based on `Next-URL` (which is used for route interception), this adjusts how we set the `Vary` header to conditionally include `Next-URL`.
The `Next-URL` request header only impacts the response for routes that are intercepted. When we detect that path we're handling could be intercepted, we add `Next-URL` to the vary. This signals in #61235 to prefix these cache entries with `nextUrl` if the response might vary based on it.
Closes NEXT-2398
### Why
The `process/browser` lib was imported and being transformed, but
`process.browser = true` turns to `true = true` that causes the
compilation error, we need to exclude them from certain compilation
layers

## History
Previously, we added support for `squoosh` because it was a wasm
implementation that "just worked" on all platforms when running `next
dev` for the first time. However, it was slow so we always recommended
manually installing `sharp` for production use cases running `next
build` and `next start`.
Now that [`sharp` supports
webassembly](https://sharp.pixelplumbing.com/install#webassembly), we no
longer need to maintain `squoosh`, so it can be removed. We also don't
need to make the user install sharp manually because it can be installed
under `optionalDependencies`. I left it optional in case there was some
platform that still needed to manually install the wasm variant with
`npm install --cpu=wasm32 sharp` such as codesandbox/stackblitz (I don't
believe sharp has any fallback built in yet).
Since we can guarantee `sharp`, we can also remove `get-orientation` dep
and upgrade `image-size` dep.
I also moved an [existing `sharp`
test](https://github.com/vercel/next.js/pull/56674) into its own fixture
since it was unrelated to image optimization.

- parsed stack traces (and error stack locations in js) have 1-based

- source map tokens have 0-based lines and 0-based columns
- babel code frames use 1-based lines and 0-based columns
This was not always respected. This preserves the 1-based lines and
columns in anything called a stack frame, 0-based lines and columns for
source map apis, and converts to babel’s format as needed.

This PR fixes `.eslintrc.json` not being created after the user runs
`next lint` and selects an option of `Strict` or `Base`.
The reason is that the lint check was looking for `pages` and
`src/pages` only. Added `app` and `src/app` to be checked also.

### What?
Fixes `setAssetPrefix` when running on a custom server using next()
function
### Why?
Looks like when we run next custom server, there are 2 instances created
to handle this case
* main server in `/server/next.ts`
* and Render server `./server/lib/render-server.ts`
The issue mainly happens when calling `setAssetPrefix` it will update
only the main server and not render server
``` javascript
const next = require('next')
const app = next({ });
app.setAssetPrefix('my-fancy-cdn/static');
app.render(); // render server is used instead of the main server
```
### How?
when calling `setAssetPrefix` on the main server also update the render
server with the same information.

### What?
Removing `autoprefixer` from the default Tailwind CSS templates. (It can
be installed afterward)
### Why?
After some investigation by @timneutkens, `autoprefixer` seems to
introduce some compilation overhead
### How?
Removing `autoprefixer` from the auto-installed dependency list, it
would be up to the developer to install this plugin if they need it.

### What?
This adds a method to optionally detect disk, network, and env access
access during a build and write this to a file.
### Why?
This will be consumed by Turborepo to determine **if** a build can be
cached, and if so, **how** it should be cached.
### How?
This implements a proxy that can be selectively applied to functions to
watch their access to disk, network, and env. For Turborepo, we only
care about what can alter the build output, to achieve this, we trace
the config load, and the static page generation.
