Greptile Summary

This PR adds RB2B website visitor identification tracking to the hosted version of Sim Studio. RB2B is a B2B lead generation service that identifies individual website visitors by matching their digital fingerprints with LinkedIn profiles, providing sales teams with person-level identification data rather than just company-level analytics.

The implementation includes two key changes to apps/sim/app/layout.tsx:

1. RB2B Script Integration: A new tracking script is injected into the HTML head that loads asynchronously from AWS S3. The script follows RB2B's standard snippet pattern with methods for identify and collect, and includes proper version tracking.

2. Analytics Simplification: The complex shouldEnableAnalytics() logic has been replaced with a simpler isHosted check for both Vercel Analytics and SpeedInsights components. This creates consistency across all tracking services.

Both changes are gated behind the isHosted condition, ensuring that only the main hosted platform (not self-hosted installations) sends visitor data to these third-party services. This approach maintains user privacy for self-hosted deployments while enabling powerful lead generation capabilities for the main SaaS offering. The RB2B integration fits into the existing analytics infrastructure by following the same conditional loading pattern already established for other tracking services.

Confidence score: 4/5

• This PR is generally safe to merge with proper monitoring of the third-party script loading
• The code follows established patterns and includes appropriate privacy controls, but introduces a third-party dependency that should be monitored
• The layout.tsx file needs attention to ensure the RB2B script loads correctly and doesn't impact performance
