[React 19] react-reconciler README is missing scheduler and form hooks

[CodyJasonBennett]

Summary

I've been working on updating the types for react-reconciler, and found methods are still missing from its README after recent updates. These are detailed in pmndrs/react-three-fiber#3242 based on implementation, but they are as follows:

• NotPendingTransition Implement experimental_useFormStatus #26722
• setCurrentUpdatePriority, getCurrentUpdatePriority, resolveUpdatePriority [Fiber] Move updatePriority tracking to renderers #28751
• resetFormInstance Automatically reset forms after action finishes #28804
• requestPostPaintCallback [Draft][Transition Tracing] More Accurate End Time #25105
• shouldAttemptEagerTransition Synchronously flush the transition lane scheduled in a popstate event #26025

I can open a PR for updating the README specifically, but I haven't looked deeper to see if there was anything else missing in the repo.

Not stale. I can try to find time to continue this.

Not stale. Haven't updated my comment since, but changes would be since last pinned RC.
