feat: Implement Phase 1 K8s agent orchestrator system

Core agent system for Raspberry Pi k0s cluster management:

Agents:
- k8s-orchestrator: Central task delegation and decision making
- k8s-diagnostician: Cluster health, logs, troubleshooting
- argocd-operator: GitOps deployments and rollbacks
- prometheus-analyst: Metrics queries and alert analysis
- git-operator: Manifest management and PR workflows

Workflows:
- cluster-health-check.yaml: Scheduled health assessment
- deploy-app.md: Application deployment guide
- pod-crashloop.yaml: Automated incident response

Skills:
- /cluster-status: Quick health overview
- /deploy: Deploy or update applications
- /diagnose: Investigate cluster issues

Configuration:
- Agent definitions with model assignments (Opus/Sonnet)
- Autonomy rules (safe/confirm/forbidden actions)

+### Pi 3 Toleration (for lightweight workloads)
+```yaml
+tolerations:
+  - key: "node-type"
+    operator: "Equal"
+    value: "pi3"
+    effect: "NoSchedule"

+
+## Response Format
+
+When reporting:
+
+1. **Operation**: What was done
+2. **Files Changed**: List of modified files
+3. **Commit/PR**: Reference to commit or PR created
+4. **Next Steps**: What happens next (ArgoCD sync, review needed)
+
+## Example Output
+
+```
+Operation: Created deployment manifest for new app
+
+Files Changed:
+- apps/myapp/deployment.yaml (new)
+- apps/myapp/service.yaml (new)
+- apps/myapp/kustomization.yaml (new)
+
+Commit: abc123 "Add myapp deployment manifests"
+Branch: feature/add-myapp
+PR: #42 "Deploy myapp to cluster"
+
+Next Steps:
+- PR requires review and merge
+- ArgoCD will auto-sync after merge to main
+```
+
+## Commit Message Format

+```
+<type>: <short description>
+
+<optional longer description>
+
+Types:
