Feature Pack 006: Observability with LGTM on Compose

Status: Implemented Track: nonfunctional Previous state: 005-messaging-nats-replacement

This pack defines the convergence C1 state after 005-messaging-nats-replacement.

Primary intent:

• add a practical LGTM observability stack on top of the containerized baseline,
• keep business flows unchanged while improving runtime visibility,
• provide prebuilt Grafana dashboards for developer/operator learning,
• keep generation fully spec-first through state patch overlays.
