Pull Request Overview

This PR adds support for handling oneOf/anyOf constructs during schema-to-Zod and schema-to-Python-TypedDict generation, accompanied by new tests and a snapshot update.

• Extend convertSchema (Zod) to emit z.union([...]) for oneOf/anyOf
• Extend convertToTypedDict (Python) to emit Union[...] for oneOf/anyOf
• Add unit tests for oneOf with refs in both Zod and TypedDict paths and update snapshot

• [nitpick] Consider adding a corresponding test for anyOf with refs to ensure consistent coverage of both union keywords in Zod generation.
