Zod Registry Error

Environment Information

Stagehand:

• Language/SDK: TypeScript
• Stagehand version: 3.0.8

AI Provider:

Issue Description

I am getting the following error after the first call to my API endpoint

Error: ID LocalBrowserLaunchOptions already exists in the registry
web-app:dev: > 1 | import { Stagehand } from "@browserbasehq/stagehand"
web-app:dev:     | ^

The issue extends from the Zod package, reported here colinhacks/zod#5481 (comment). Though it has since been fixed in Zod v4.3.0.

Steps to Reproduce

1. NextJS app with ElysiaJS as API backend
2. Call API endpoint that imports Stagehand and observe it works successfully
3. Call the same API endpoint again and observer the Error: ID LocalBrowserLaunchOptions already exists in the registry error.

Minimal Reproduction Code

I do not have one.
