Phase 6.6: Add Poimen Memory DLQ queues (ArgoCD managed)

ArgoCD Application: memory-queues
  ├─ Sync wave: 7 (messaging wave)
  ├─ Path: k8s/apps/messaging/memory-queues
  ├─ Namespace: sqs
  └─ Auto-sync: enabled (prune + selfHeal)

Helm Chart: memory-queues
  ├─ Chart.yaml: v0.1.0
  ├─ values.yaml: Queue config
  └─ templates/queues.yaml: Queue CRD resources

Queues Created:

1. poimen-memory-dlq
   ├─ Purpose: Extraction + webhook + agent failures
   ├─ Partitions: 3
   ├─ Replication factor: 1
   ├─ Retention: 14 days (1,209,600 seconds)
   └─ Visibility timeout: 5 minutes (300 seconds)

2. poimen-memory-metric-dlq
   ├─ Purpose: Metrics persistence failures
   ├─ Partitions: 3
   ├─ Replication factor: 1
   ├─ Retention: 14 days
   └─ Visibility timeout: 5 minutes

Resource: Queue CRD (kmsvc.io/v1alpha1)
  └─ Managed by: queue-operator (already running in sqs ns)

Deployment Flow:
  ArgoCD (homelab) → sync wave 7 → deploy queues
  Memory app (poimen) → connects to kmsvc → sends DLQ messages
