### What?
The updates `edge-runtime` to the latest version
### Why?
https://github.com/vercel/edge-runtime/pull/428 fixes `consumeUint8ArrayReadableStream` so that when we break iteration early (due to client disconnect), we cleanup the inner stream. That will fire the stream's `cancel` handler, and allow devs to disconnect from an AI service fetch.
### How?
`edge-runtime` maintain a `try {} finally {}` over the inner stream's iteration. When we early break, JS will call `it.return()`, and that will resume `consumeUint8ArrayReadableStream` with an abrupt completion (essentially, the `yield` turns into a `return`). We'll be able to trigger the `finally {}` block with that, and we call `inner.cancel()` to cleanup.
Fixes https://github.com/vercel-labs/ai/issues/90
To resolve issue #49382, we found layer doesn't get applied for dynamic imports, so we fixed it on webpack side in https://github.com/webpack/webpack/pull/17310
This PR is to upgrade webpack to 5.86.0 with that patch as a precedence. After this we need to fix the `next/image` client components is missing in client reference manifest when using dynamic imports to fix the issue.
Hello,
We removed some core non-necessary dependencies that make Edge Runtime
smaller 🙂.
Also, Edge Runtime is exposing `WebSocket`, so nothing additional should
be done.
Closes https://github.com/vercel/next.js/issues/50760
