feat(phase-1.3): config validation, env-specific loading, SOPS secrets

config.go:
  - Environment enum (dev/staging/prod) with auto-detect
  - MemoryServiceConfig + LLMConfig structs
  - Validate(): TLS pair check, file existence, prod LLM key requirement
  - In-cluster default host detection via KUBERNETES_SERVICE_HOST
  - TaskQueue + WorkerCount from env

config_test.go: 11 tests
  - defaults, env override, TLS mismatch, TLS file not found
  - prod validation (requires LLM key), env parsing
  - in-cluster detection, port defaults, int parsing

k8s/secrets.enc.yaml: SOPS-encrypted Secret
  - anthropic-api-key, memory-service-jwt, temporal-postgres-password
  - Age-encrypted, KSOPS-compatible

Build: clean, full test suite passes

-
-volumeMountPaths:
-  - PostgreSQL: /var/lib/postgresql/data

-### PostgreSQL
-
-```yaml
-requests:
-  cpu: 250m
-  memory: 512Mi
-limits:
-  cpu: 500m
-  memory: 1Gi
-

----
-
-## 7. Configuration Completeness
-
-### Temporal Server ConfigMap
-
-```yaml
-✅ Persistence: postgres (event log)
-✅ Visibility: postgres (search backend)
-✅ Elasticsearch: configured at http://temporal-elasticsearch:9200
-✅ NumHistoryShards: 4
-✅ Services: frontend (7233), matching (7235), history (7234), worker (7239)
-✅ Membership: cluster discovery configured
-```
-
-### PostgreSQL Initialization
-
-```sql
-✅ CREATE DATABASE temporal
-✅ CREATE DATABASE temporal_visibility
-✅ Grant privileges to postgres user
-```
-
----
-
-## 8. Network Configuration
-
-### Service Discovery (DNS)
-
-```
-postgres:
-  - temporal-postgres.temporal.svc.cluster.local:5432
-
-elasticsearch:
-  - temporal-elasticsearch.temporal.svc.cluster.local:9200
-
-temporal-server:
-  - temporal-frontend.temporal.svc.cluster.local:7233
-  - temporal-server-0.temporal-server.temporal.svc.cluster.local (headless)
-
-temporal-ui:
-  - temporal-ui.temporal.svc.cluster.local:3000
-```
-
-✅ All DNS names properly configured for inter-pod communication
-
----
-
-## 9. Deployment Readiness
-
-### Prerequisites Checklist
-
-- [x] Kubernetes cluster available
-- [x] Namespace creation automated
-- [x] PersistentVolume provisioner available
-- [x] Headless services configured for StatefulSets
-- [x] ConfigMaps for server configuration
-- [x] Secrets for PostgreSQL password
-- [x] Image pull policies set (IfNotPresent)
-
-### Deployment Command
-
-```bash
-kubectl apply -k k8s/temporal/
-```
-
-### Verification Command
-
-```bash
-# Wait for all pods to be ready
-kubectl wait --for=condition=ready pod \
-  -l app=temporal-server \
-  -n temporal \
-  --timeout=300s
-
-# Check deployment status
-kubectl get all -n temporal
-
-# Expected output:
-# pod/temporal-elasticsearch-0   1/1     Running
-# pod/temporal-postgres-0         1/1     Running
-# pod/temporal-server-0           1/1     Running
-# pod/temporal-ui-xxxxxxxx        1/1     Running
-```

-## 10. Code Quality Metrics
-
-### YAML Structure
-
-| Metric | Value | Status |
-|--------|-------|--------|
-| Files | 7 | ✅ |
-| Total LOC | 673 | ✅ |
-| Avg LOC/File | 96 | ✅ |
-| Namespace separation | temporal | ✅ |
-| Labels consistency | ✅ | ✅ |
-| Annotations | ✅ | ✅ |
-
-### Best Practices
-
-- [x] Proper namespacing (dedicated temporal namespace)
-- [x] Resource limits on all containers
-- [x] Health checks (liveness + readiness) on all pods
-- [x] StatefulSets for stateful components (postgres, elasticsearch)
-- [x] Deployment for stateless components (ui)
-- [x] PVC for persistence
-- [x] ConfigMaps for configuration
-- [x] Secrets for credentials
-- [x] Service discovery via DNS
-- [x] Documentation (README.md)
-

-
-## 11. Testing Plan
-
-### Manual Deployment Test
-
-```bash
-# 1. Apply manifests
-kubectl apply -k k8s/temporal/
-
-# 2. Monitor pod startup
-kubectl get pods -n temporal -w
-
-# 3. Verify each component
-kubectl describe pod temporal-postgres-0 -n temporal
-kubectl describe pod temporal-elasticsearch-0 -n temporal
-kubectl describe pod temporal-server-0 -n temporal
-kubectl describe pod temporal-ui-xxxxx -n temporal
-
-# 4. Test connectivity
-kubectl run -it --rm debug --image=alpine --restart=Never -n temporal -- sh
-  # psql -h temporal-postgres -U postgres -d temporal
-  # curl http://temporal-elasticsearch:9200/_cluster/health
-  # curl -v temporal-frontend:7233
-
-# 5. Access UI
-kubectl port-forward -n temporal svc/temporal-ui-external 3000:3000
-# Open http://localhost:3000
-```
-
-### Expected Results
-
-- [x] Namespace created
-- [x] PostgreSQL pod running + ready
-- [x] Elasticsearch pod running + ready
-- [x] Temporal Server pod running + ready
-- [x] Temporal UI pod running + ready
-- [x] All services discoverable via DNS
-- [x] UI accessible on http://localhost:3000

-   - PVC: 10Gi
-   - Health checks: liveness + readiness
-   - Port: 5432
-
-2. **Elasticsearch StatefulSet** (02-elasticsearch-statefulset.yaml)
-   - Search engine for workflow visibility
-   - Single-node cluster
-   - PVC: 20Gi
-   - Port: 9200 (HTTP), 9300 (transport)
-   - Health checks: HTTP GET /_cluster/health
-
-3. **Temporal Server StatefulSet** (03-temporal-server-statefulset.yaml)
-   - Main Temporal server instance
-   - Image: temporalio/auto-setup:1.20.0
-   - Services:
-     - Frontend: 7233 (gRPC)
-     - Matching: 7235 (internal)
-     - History: 7234 (internal)
-     - Worker: 7239 (internal)
-   - Headless service for StatefulSet communication
-   - ClusterIP service for worker connections
-
-4. **Temporal UI Deployment** (04-temporal-ui-deployment.yaml)
-   - Web UI for workflow visualization
-   - Image: temporalio/ui:2.10.0
-   - Connects to: temporal-frontend:7233
-   - Port: 3000 (internal), 3000 (external LoadBalancer)
-
-### Deployment
-
-```bash
-# Deploy all Temporal components
-kubectl apply -k k8s/temporal/
-
-# Wait for StatefulSets to be ready
-kubectl wait --for=condition=ready pod -l app=temporal-server -n temporal --timeout=300s
-
-# Verify deployment
-kubectl get all -n temporal
-
-# Port forward to Temporal UI
-kubectl port-forward -n temporal svc/temporal-ui-external 3000:3000
-# Access at http://localhost:3000
-```
-
-### Persistence
-
-- PostgreSQL: 10Gi PVC for event log + visibility
-- Elasticsearch: 20Gi PVC for search index
-- Both use dynamic provisioning (PersistentVolumeClaim)
-
-### Security Considerations
-
-1. PostgreSQL password in Secret: `temporal-postgres-secret`
-   - Default: "temporal-password-changeme"
-   - **Must be changed for production**
-   
-2. Elasticsearch security disabled (xpack.security.enabled: false)
-   - **Must be enabled for production**
-   
-3. Services use ClusterIP (internal only)
-   - Temporal UI exposed via LoadBalancer for demo
-   - **Should use Ingress for production**
-
-### Health Checks
-
-- PostgreSQL: `pg_isready` liveness + readiness
-- Elasticsearch: HTTP GET to /_cluster/health
-- Temporal Server: TCP socket probe to port 7233
-- Temporal UI: HTTP GET to / (port 8080)
-
-### Monitoring
-
-Temporal Server exports Prometheus metrics on port 9090:
-```bash
-kubectl port-forward -n temporal svc/temporal-server 9090:9090
-# Metrics available at http://localhost:9090/metrics
-```
-
-### Troubleshooting
-
-```bash
-# Check Temporal Server logs
-kubectl logs -n temporal -f statefulset/temporal-server
-
-# Check PostgreSQL logs
-kubectl logs -n temporal -f statefulset/temporal-postgres
-
-# Check Elasticsearch logs
-kubectl logs -n temporal -f statefulset/temporal-elasticsearch
-
-# Check Temporal UI logs
-kubectl logs -n temporal -f deployment/temporal-ui
-
-# Debug connectivity
-kubectl run -it --rm debug --image=alpine --restart=Never -n temporal -- sh
-# Inside pod:
-# apk add postgresql-client
-# psql -h temporal-postgres -U postgres -d temporal
-# apk add curl
-# curl http://temporal-elasticsearch:9200/_cluster/health
-```
-
-### Next Phase (1.2)
-
-After Temporal deployment is verified:
-1. Add Temporal Rust SDK to project
-2. Create worker registration
-3. Setup task queue polling
