prefetching is now controlled with the prefetch export and this option is inert on the instant export. this removes the prefetch option as a valid property on the instant config type.

also updates the ts plugin for this export and adds the definition for the previously landed prefetch export

Additional Suggestion:

TypeScript plugin autocomplete for unstable_instant suggests { prefetch: "static" } which is rejected by the strict Zod schema that no longer includes a prefetch property, and the type hint is missing true as a valid value.
