value the parent snapshot has is not considered a conflict."

A policy to treat values of a `MutableState` as equivalent if they are structurally (==) equal.

Setting `MutableState.value` to its current structurally (==) equal value is not considered a
change. When applying a `MutableSnapshot`, if the snapshot changes the value to the equivalent
value the parent snapshot has is not considered a conflict.
