feat(prod): complete production deployment with Podman containerization

- Migrate from Docker to Podman for enhanced security (rootless containers)
- Add production-ready Dockerfile with multi-stage builds
- Configure production environment with Arbitrum mainnet RPC endpoints
- Add comprehensive test coverage for core modules (exchanges, execution, profitability)
- Implement production audit and deployment documentation
- Update deployment scripts for production environment
- Add container runtime and health monitoring scripts
- Document RPC limitations and remediation strategies
- Implement token metadata caching and pool validation

This commit prepares the MEV bot for production deployment on Arbitrum
with full containerization, security hardening, and operational tooling.
