+Add Zod 4 support. You can now use Zod 3.25.76+ or Zod 4.

 ## Dependency Pinning
 
-Zod is pinned to a single version across the entire monorepo (currently `3.25.76`). When adding zod to a new or existing package, use the **exact same version** as the rest of the repo - never a different version or a range. Mismatched zod versions cause runtime type incompatibilities (e.g., schemas from one package can't be used as body validators in another).
