⚠️ Breaking Changes

• Build custom-operation leaf fields per query (#448)

  Custom-operation leaf fields are now built per query, on access, instead of eagerly during generation. This also fixes a case where a custom scalar mapped to a non-builtin type (e.g. Decimal) used in a custom-operation argument produced a custom_fields.py/custom_queries.py that raised NameError on import due to a missing import.
