mainThreadLayoutState

Kotlin property alias for _mainThreadLayoutState.

This property is hidden from Java callers via @JvmSynthetic, so Java code will continue to use getMainThreadLayoutState. The @JvmName annotation provides a unique JVM name to avoid conflicts with the existing getter method. Kotlin callers can use this property directly (e.g., componentTree.mainThreadLayoutState).

NOTE: This getter delegates to getMainThreadLayoutState to ensure that mocking the method in tests also affects the Kotlin property accessor.
