feat: Add HMMM traffic monitoring tool

Create standalone monitoring container that subscribes to all CHORUS
pub/sub topics and logs traffic in real-time for debugging and observability.

Features:
- Subscribes to chorus-bzzz, chorus-hmmm, chorus-context topics
- Logs all messages with timestamps and sender information
- Pretty-printed JSON output with topic-specific emojis
- Minimal resource usage (256MB RAM, 0.5 CPU)
- Read-only monitoring (doesn't publish messages)

Files:
- hmmm-monitor/main.go: Main monitoring application
- hmmm-monitor/Dockerfile: Multi-stage build for minimal image
- hmmm-monitor/docker-compose.yml: Swarm deployment config
- hmmm-monitor/README.md: Usage documentation

This tool helps debug council formation, task execution, and agent
coordination by providing visibility into all HMMM/Bzzz traffic.
