Summary
Today, when a Server Action request reaches a route whose worker does not bundle that action, Next.js consults the Server Action manifest and internally forwards the request to another worker. It has caused correctness issues and miscellaneous bugs because the action executes under a different route and request context.
The preceding PR adds direct action dispatch: the client learns which route owns an action and sends the request directly to that route.
With direct dispatch in place, this removes the internal forwarding request, worker-selection logic, and
x-action-forwardedhandling. A valid action sent to the wrong route now returns the standard action-not-found response instead of being forwarded.Supersedes #90549
