This adds a guard for whenever we do a hard navigation over a client-navigation to ensure we aren't redirecting to the same URL that we are currently on as this can cause infinite redirecting. This also fixes some cases with middleware rewrites without i18n enabled and expands our middleware suite to test both with i18n and without.
This also fixes a race condition with the query updating where a user could attempt a route transition and it then gets overridden by the query updating and prevents firing router events during the query updating as these can be false signals of a transition.

Fixes: https://github.com/vercel/next.js/issues/37804
Follow-up to https://github.com/vercel/next.js/pull/31519 this ensures the error link we added is shown with react 18 as well.

For streaming, we want the main bundle to be loaded with `async` rather than `defer`. As the first step to doing that, we need an explicit initialization step, rather than occurring as a side effect of being loaded.
For now, I've just split the logic into a `initialization` and `hydrate` (previously `initNext`) functions and called them as a side effect of `next/client/next` and `next/client/next-dev` as before. A follow-up PR will move that to a separate script tag [as recommended](https://github.com/reactwg/react-18/discussions/114).
This adds an error document/link for hydration errors to help users debug these easier. While looking at adding this also noticed a typo in the dev-overlay which is fixed.

When you edit your code, and Next.js is compiling the application, a compilation indicator appears in the bottom right corner of the page.
In some cases this indicator can be misplaced on the page, for example, when conflicting with a chat launcher. To change its position, open `next.config.js` and set the `buildActivityPosition` in the `devIndicators` object to `bottom-right` (default), `bottom-left`, `top-right` or `top-left`.
I also added the documentation for both `devIndicators.buildActivity` & the new `devIndicators.buildActivityPosition`.

This replaces the server-sent events HMR connection with a WebSocket connection to prevent hitting browser connection limits, allow sending events back from the browser, and overall better performance.
This approach sets up the the `upgrade` event listener on the server immediately when created via `next dev` and on the first request using `req.socket.server` when created via a custom server. In a follow-up PR we can push the files changed via the WebSocket as well.

### move all access to built pages into worker pool
to allow parallelizing and avoid loading the bundles in the main thread
This improves performance of the static check step a bit and helps reducing memory load in main thread
### enable splitChunks for server build in webpack 5
This improves performance for static generation by loading less code due to reduced duplication
Just cleans up some code, doesn't change the underlying mechanism

This adds initial support for reloading the page when `getStaticProps`, `getStaticPaths`, or `getServerSideProps` were changed for a page by triggering a reload when the server output for a page has changed but the client output has not since these methods aren't included in the client output.
