Special Note: zod v4

This beta release adds support for zod v4, a highly requested addition.

Special thanks to @dclark27 @colinhacks for all the work on #1040 which adds this support while staying backwards compatible with zod v3!

NOTE: if you run into any issues with zod v4 in this SDK please raise an issue! We'll be monitoring actively for any issues while trying to use zod v4 as it's a highly anticipated update. In order to make this upgrade possible we needed to also require v3.25+ for zod v3. You may need to update your version of zod v3 if you've been using an older one. We're also making this a beta release while we get initial feedback on the update here.
