Purpose
SimpleStatsEvolutions._create_index_cast_mapping was using field.name to build the mapping between table schema and data schema. This breaks after column renames because names change while field IDs remain stable. Changed to use field.id, aligning with Java's SchemaEvolutionUtil.createIndexMapping.
