Cross-Chain Vita Verification Test
This script tests the Federation contract's cross-chain Vita verification
between Alpha (network 88890) and Beta (network 88891) instances.
Test Flow:
1. Verify Federation contract on both chains
2. Check current visitor registrations
3. Register a visitor on Beta from Alpha
4. Verify the visitor can be recognized on Beta

When a citizen from Alpha visits Beta:

- Citizen has Vita token (soul-bound identity)

2. CROSS-CHAIN BRIDGE (Off-chain):
- Citizen presents proof of Vita ownership to Beta
- Beta government verifies via bridge protocol (Pons contract)
3. BETA CHAIN (Host):
- Committee calls: Federation.registerVisitor(owner, 88890)
- Visitor is now recognized on Beta
- Transaction fees are split:
* {fee_percent}% paid by Beta Treasury (host subsidy)
* {remaining}% added to inter-chain debt (owed to Alpha)
4. VERIFICATION:
- Any contract can call: Federation.isVisitor(owner) -> true
- Get home chain: Federation.getHomeChain(owner) -> 88890
- Visitor can access services on Beta chain
