Fix JSON Schema reference resolution: kotlin.NotImplementedError: Cannot resolve ref path: #/$defs/CreditTransferTransaction39

[wuseal]

Problem

When using newer JSON Schema formats that use `` instead of definitions, the plugin crashes with error: "Cannot resolve ref path: #//...".

Solution

• Added support for newer JSON Schema format using `` instead of definitions
• Created helper method to combine both definitions and into a single map
• Enhanced JSON Schema detection to recognize schemas with ``
• Added comprehensive test cases for `` support
• Fixed crash when resolving references to #// paths

This PR resolves the crash reported in the logs where the plugin was unable to parse JSON Schema using the newer `` format.
