`shallow` doesn't correctly compare different object instances if they only have property getters

[tcgj]

Describe the bug

I'm using @tanstack/react-form, but traced the issue back to the store here. Specifically, I'm trying to store Temporal.Duration values, but store updates are not being received via useStore because shallow returns true when both objects have no keys, i.e. Object.keys(objA) return [], instead of comparing referential equality at that point.

Steps to Reproduce the Bug or Issue

This, and any object factory that use getters instead of static properties return true.

shallow(Temporal.Duration.from({ hours: 1 }), Temporal.Duration.from({ days: 2 }));

Expected behavior

Expect to see false, since they are different values, different objects.
