#3613 feat(taps): Normalize two-element `oneOf` schema members where one of them is the null type, into a single nullable schema Pull request opened by edgarrmondragon SSIA Summary by Sourcery Normalize JSON schemas that use two-element oneOf with a null branch into a single nullable schema representation and centralize oneOf handling logic. New Features: • Support normalization of two-element oneOf schemas where one branch is the null type into compact nullable type schemas, including nested object properties. Enhancements: • Refactor oneOf processing into a dedicated handler used by normalize_schema to simplify and unify oneOf normalization behavior. Tests: • Add parametrized tests covering normalization of nullable oneOf schemas for primitives and objects, ensuring oneOf removal and correct nullable type shaping. meltano/sdk
