refactor(deps): move zod from dependencies to peerDependencies

Move zod to peerDependencies with range '>=3.25.0 <5' to align with
AI SDK compatibility requirements. This allows users to provide their
own zod version, avoiding duplicate installations and ensuring type
compatibility when using zod schemas with AI SDK.

Changes:
- Remove zod from dependencies
- Add zod to peerDependencies (>=3.25.0 <5)
- Add zod to devDependencies for testing (^4.1.13)
- Update pnpm-workspace.yaml catalogs accordingly
