Goal Add and Mul translate their operands through the same normalized code path Div and Sub already use, so each operand can independently be a group of columns, a single column, a constant scalar or a constant list. Div (#129) and Sub (#127) are both on main already, and they share the GraphVariables.consume_operand_values() helper that does the normalization. Add and Mul are the two remaining translators still carrying the pre-refactor shape. Done when: add.py and mul.py obtain both operands via self._variables.consume_operand_values() and follow the same keys/values flow as div.py and sub.py, instead of pre-committing with get_initializer_value() and treating a computed operand as an error. Each supports the operand matrix Div and Sub support, including group + computed column, column + column and constant + column. group + single constant broadcast works; it currently raises ValueError in both Add and Mul. The error text no longer calls the second operand a "divisor" (add.py:28, m
