Patch Changes

• #486 64d0c6e Thanks @hyesungoh! - buildContext now sets displayName on the returned Provider to `${contextName}Provider`, so React DevTools shows which context a provider belongs to instead of a bare Provider. The documentation example also passed null as the default values, which the signature rejects; it now passes an object.

• #484 c974fdc Thanks @hyesungoh! - useControlledState now applies multiple setValue calls in the same tick in order when uncontrolled, instead of computing each from the value captured at render. This affects both function updates and plain values: setValue(prev => prev + 3) twice now adds 6 instead of 3, and setValue('b') followed by setValue('a') from a current value of 'a' now settles on 'a' instead of 'b'.

  As a consequence, in uncontrolled mode onChange is called once after the state commits with the final value, rather than synchronously on every setValue call. A parent that mirrors onChange into its own state therefore renders once more per update, no call is made when the final value equals the previous one, and a change reported by a component that unmounts in the same commit is dropped. Under StrictMode a single change is now reported once instead of twice.

  Controlled mode is unchanged: it still computes from the current value prop, so two function updates in the same tick see the same previous value.

• #486 64d0c6e Thanks @hyesungoh! - mergeRefs now forwards the cleanup functions that callback refs can return since React 19. When at least one of the merged refs returns a cleanup, the merged ref returns one as well, so React runs those cleanups on detach instead of calling the callbacks with null; refs that returned nothing are still reset to null inside that cleanup. When no ref returns a cleanup the merged ref returns nothing, as before, so React 18 keeps its existing null call and does not warn.
