Epic Goal: Scale network and storage for production workloads.
Scope: Complete libp2p integration with full DHT, NAT traversal, expand RocksDB with snapshots/pruning, add WebSocket API.
Success Criteria:
- ✅ Network survives 3+ node testnet for 1 week
- ✅ State persistence with snapshots/pruning
- ✅ Real-time WebSocket subscriptions
- ✅ Compact blocks reduce bandwidth 80%
Dependencies: Requires RC1 networking (#35) and state (#37)
