refactor: consolidate type-check helpers into generic wrenIsObjType and validate IS operand is class

Replace six separate type-check functions (wrenIsClosure, wrenIsFiber, wrenIsFn, wrenIsInstance, wrenIsRange, wrenIsString) with a single wrenIsObjType that takes an ObjType parameter. Add IS_CLASS macro and runtime validation in the IS bytecode handler to ensure the right operand is a class, producing a clear error message when it is not. Add test case for non-class right operand.
