Support for Zod 4

[kentkwu]

Hi all. I'm very interested in trying this library, however I have a codebase that is already using Zod v4.

Any interest in adding Zod 4 compatibility?

I took a cursory look through the project and the surface area of this change should be pretty small. Happy to contribute a PR.

// package.json
{
  "peerDependencies": {
    "zod": "^3.25.0 || ^4.0.0"
  }
}

From the library authors guide: https://zod.dev/library-authors

Hi @kentkwu

This is required because of the mcp sdk dependency: https://github.com/modelcontextprotocol/typescript-sdk/blob/main/package.json.

We don't have a direct dependency on zod 3

A pull request to support Zod V4 is pending on their side: modelcontextprotocol/typescript-sdk#869

Hi guys
ATM, is there a way to be able to use this lib with Zod 4 ? Can be a dirty fix, while waiting for the mcp ts sdk PR to be merged
