Module cross_chain 

Cross-Chain Right Transfer

Implements the lock-and-prove protocol for transferring Rights between chains:

1. Lock — Source chain consumes seal, emits CrossChainLockEvent
2. Prove — Client generates inclusion proof
3. Verify — Destination chain verifies proof, checks registry, mints new Right
4. Registry — Records transfer, prevents cross-chain double-spend
