- Switched to Zod 4:

- Minimum supported version of `zod` is 4.0.0;

- ⚠️This version might not support all new features of Zod 4;

- `IOSchema` type had to be simplified down to a schema resulting in a `object`, but not an `array`;

- Despite supporting examples by the new Zod method `.meta()`, users should still use `.example()` to set them;

- Refer to [Migration guide on Zod 4](https://v4.zod.dev/v4/changelog) for adjusting your schemas;
