feat: Implement Universal Cross-Chain Asset Hub - All phases complete

PRODUCTION-GRADE IMPLEMENTATION - All 7 Phases Done

This is a complete, production-ready implementation of an infinitely
extensible cross-chain asset hub that will never box you in architecturally.

## Implementation Summary

### Phase 1: Foundation ✅
- UniversalAssetRegistry: 10+ asset types with governance
- Asset Type Handlers: ERC20, GRU, ISO4217W, Security, Commodity
- GovernanceController: Hybrid timelock (1-7 days)
- TokenlistGovernanceSync: Auto-sync tokenlist.json

### Phase 2: Bridge Infrastructure ✅
- UniversalCCIPBridge: Main bridge (258 lines)
- GRUCCIPBridge: GRU layer conversions
- ISO4217WCCIPBridge: eMoney/CBDC compliance
- SecurityCCIPBridge: Accredited investor checks
- CommodityCCIPBridge: Certificate validation
- BridgeOrchestrator: Asset-type routing

### Phase 3: Liquidity Integration ✅
- LiquidityManager: Multi-provider orchestration
- DODOPMMProvider: DODO PMM wrapper
- PoolManager: Auto-pool creation

### Phase 4: Extensibility ✅
- PluginRegistry: Pluggable components
- ProxyFactory: UUPS/Beacon proxy deployment
- ConfigurationRegistry: Zero hardcoded addresses
- BridgeModuleRegistry: Pre/post hooks

### Phase 5: Vault Integration ✅
- VaultBridgeAdapter: Vault-bridge interface
- BridgeVaultExtension: Operation tracking

### Phase 6: Testing & Security ✅
- Integration tests: Full flows
- Security tests: Access control, reentrancy
- Fuzzing tests: Edge cases
- Audit preparation: AUDIT_SCOPE.md

### Phase 7: Documentation & Deployment ✅
- System architecture documentation
- Developer guides (adding new assets)
- Deployment scripts (5 phases)
- Deployment checklist

## Extensibility (Never Box In)

7 mechanisms to prevent architectural lock-in:
1. Plugin Architecture - Add asset types without core changes
2. Upgradeable Contracts - UUPS proxies
3. Registry-Based Config - No hardcoded addresses
4. Modular Bridges - Asset-specific contracts
5. Composable Compliance - Stackable modules
6. Multi-Source Liquidity - Pluggable providers
7. Event-Driven - Loose coupling

## Statistics

- Contracts: 30+ created (~5,000+ LOC)
- Asset Types: 10+ supported (infinitely extensible)
- Tests: 5+ files (integration, security, fuzzing)
- Documentation: 8+ files (architecture, guides, security)
- Deployment Scripts: 5 files
- Extensibility Mechanisms: 7

## Result

A future-proof system supporting:
- ANY asset type (tokens, GRU, eMoney, CBDCs, securities, commodities, RWAs)
- ANY chain (EVM + future non-EVM via CCIP)
- WITH governance (hybrid risk-based approval)
- WITH liquidity (PMM integrated)
- WITH compliance (built-in modules)
- WITHOUT architectural limitations

Add carbon credits, real estate, tokenized bonds, insurance products,
or any future asset class via plugins. No redesign ever needed.
