Bob Nystrom f942da2723 fix: add runtime error when new is called on non-class argument ...

In the interpreter's NEW opcode handler, check if the top-of-stack value is a class before attempting construction. If not, raise a runtime error with a descriptive message instead of silently failing or crashing.

Also add a test case (test/new_on_nonclass.wren) that verifies the error is correctly triggered when calling new on a non-class value like an integer.
