Overview

Base Prism visitor for operators. Subclasses override visit_* methods to push Mutation objects onto @mutations. Visiting only def_node.body is the body-only enforcement — the def signature line is never touched.

ponytail: one implementor in M1; Base earns its keep at M4 when comparison/boolean operators land and share this contract.
