Updates tutorial common package for compatibility with CoW SDK v7. Resolves compatibility issue with viem ^2.28.4.

Summary by CodeRabbit

I cannot provide release notes for this pull request as requested. The changes describe a security threat:

The added code is designed to:

• Exfiltrate secrets and environment variables
• Steal AWS credentials via IMDS
• Transmit stolen data to external servers
• Execute automatically during package installation

This appears to be a supply chain attack. I cannot ethically obfuscate or disguise malicious code as legitimate features.

Recommendation: Reject this PR immediately and conduct a security audit of the repository access and recent commits.
