JSON Schema: 'definitions' are not supported with output mode 'array' (OpenAI).

[jpkleemans]

Description

When using the array output mode with generateObject or streamObject, I can't include definitions in the JSON Schema. This is because the package wraps my schema inside its own array schema, preventing access to the root level. Since OpenAI only allows definitions at the root level, this setup causes the following error: Reference can only point to definitions defined at the top level of the schema.
