Greptile Overview

Greptile Summary

Added ws, playwright, and playwright-core to serverExternalPackages to prevent Next.js from bundling these native modules (which can cause build failures). Also configured outputFileTracingIncludes to ensure these dependencies are properly included in the serverless function bundle for the /api/tools/stagehand/* routes.

• Externalizes ws and playwright packages from Next.js bundling to avoid native module compilation issues
• Adds outputFileTracingIncludes to ensure stagehand API routes have access to ws and playwright in production deployments

Confidence Score: 5/5

• This PR is safe to merge - it's a standard Next.js configuration fix for native module bundling
• The changes are minimal, well-targeted configuration adjustments to next.config.ts. Adding packages to serverExternalPackages and outputFileTracingIncludes is a common pattern for handling native Node.js modules in Next.js deployments.
• No files require special attention
