- Added normalizeMixedSchemaNode() function to recursively convert mixed JTD and JSON Schema definitions into valid JSON Schema. - Changed output schema validation to gracefully fall back to unconstrained JSON objects when schema is invalid instead of throwing errors. - Fixed handling of mixed JTD and JSON Schema output definitions by normalizing them during schema conversion. - Added comprehensive test coverage for JTD-to-JSON Schema conversion and output schema validation edge cases.
