Error when using recursive property in zod since 4.1

[defless]

Since updating ai sdk from 4.0 to 4.1 i got this error:

Recursive reference detected at #/properties/content/items/anyOf/4/anyOf/1/properties/content/items/anyOf/11/properties/cols/items/properties/content/items/anyOf/1! Defaulting to any

it seems related to the use of z.lazy()(references) in my zod schemas. Probably since 33592d2

Isn't

ai/packages/ui-utils/src/zod-schema.ts

Line 11 in 39af38f

$refStrategy: 'none', // no references (to support openapi conversion for google)

causing the issue ? If its the case, we must be able to override this parameter
