Introduce a new static method `Object.same(obj1, obj2)` that exposes the VM's built-in equality semantics (`wrenValuesEqual`) directly, bypassing any user-defined `==` overrides. This required creating a dedicated metaclass for Object (subclass of Class) to host the static method without polluting every class with a `same` method. The implementation wires up a new `Object metaclass` in the core initialization sequence, adjusts the class hierarchy setup order, and adds comprehensive tests covering value types, identity comparison, and verification that `Object.same` ignores custom `==` operators.
