Pull request overview

This PR refactors the property handling logic in OpenAPI schema processing to properly collect and merge properties from schemas using allOf. The implementation extracts common property processing logic into reusable helper functions and adds special handling for allOf schemas to collect properties from all sub-schemas and merge them correctly, including proper handling of required field annotations.

Key Changes

• Extracted property processing logic into processSchemaProperties helper function
• Added mergeProperties helper to merge properties with later definitions overriding earlier ones
• Implemented allOf handling that recursively collects and merges properties from all schemas in the allOf array
