Add CODE_SUPER_0 through CODE_SUPER_16 bytecodes to the VM for invoking inherited methods, along with a `namedCall` compiler helper that parses method names and argument lists after a dot. The interpreter dispatches super calls by walking up the class hierarchy from the receiver's immediate class, skipping methods defined on that class. Includes three test cases covering calling a different superclass method, calling the same method name, and indirectly inherited methods. Also fixes error formatting to handle newline tokens gracefully and adds a TODO note about not deduplicating placeholder constants for super calls.
