JSON Schema Compatibility

Converts JSON Schema v3 schemas to v4 compatibility, solving the problem of migrating legacy schemas to the newer draft. Version 1.1.0 is the latest stable release; the project appears to be in maintenance mode with no recent updates. Unlike alternatives that require manual rewriting, this tool works in-place on schema objects and supports merged syntaxes like mixed boolean/array 'required'.
