feat: implement AITBC mesh network deployment infrastructure

✅ Phase 0: Pre-implementation checklist completed
- Environment configurations (dev/staging/production)
- Directory structure setup (logs, backups, monitoring)
- Virtual environment with dependencies

✅ Master deployment script created
- Single command deployment with validation
- Progress tracking and rollback capability
- Health checks and deployment reporting

✅ Validation script created
- Module import validation
- Basic functionality testing
- Configuration and script verification

✅ Implementation fixes
- Fixed dataclass import in consensus keys
- Fixed async function syntax in tests
- Updated deployment script for virtual environment

🚀 Ready for deployment: ./scripts/deploy-mesh-network.sh dev
