### What
Support `scroll={false}` for Link component in app router. This can be
used when you don't need to scroll back to top again when route url
changes. For instance hash query changes, if you want to keep the
scrolling as it is, you can use this option.
### How
Handling the `scroll` option in navigation reducer on client side.

## What?
Removes `experimental.appDir` this was leftover from when I flipped the
switch.
Kept the config file as in the future we might add future flags and
such. It also helps that it has the types comment included so you always
get types.
