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. 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
