 feat(schema): add support for JSON Schema $defs and definitions (#146) 
Added support for $defs and definitions properties in JsonSchema record to handle JSON Schema references properly. Added tests to verify both formats work correctly.

The JsonSchema test approach uses serialization/deserialization round-trip validation instead of property-by-property assertions. This makes tests more maintainable and less likely to break when new properties are added.
