feat: add superchain-native-messaging-tutorial

[jadonamite]

Summary

Adds a new cookbook entry for Superchain Native Message Passing.

Content

• Author: @jadonamite
• Topic: Interoperability (L2-to-L2).
• Key Concepts:
  • Usage of L2ToL2CrossDomainMessenger (0x4200...0023).
  • Cross-chain validation logic (checking crossDomainMessageSender).
  • Handling circular dependencies in deployment via setter functions.

Motivation

With the Superchain expanding, developers need native examples of how to pass messages between Base and other OP Chains (like Optimism) without relying on L1 or third-party bridges.

Verification

• Tested contracts on Base Sepolia -> OP Sepolia.
• Verified message propagation and state update on destination.
