Implement programmer agent system and consolidate agent infrastructure

Programmer Agent System:
- Add programmer-orchestrator (Opus) for workflow coordination
- Add code-planner (Sonnet) for design and planning
- Add code-implementer (Sonnet) for writing code
- Add code-reviewer (Sonnet) for quality review
- Add /programmer command and project registration skill
- Add state files for preferences and project context

Agent Infrastructure:
- Add master-orchestrator and linux-sysadmin agents
- Restructure skills to use SKILL.md subdirectory format
- Convert workflows from markdown to YAML format
- Add commands for k8s and sysadmin domains
- Add shared state files (model-policy, autonomy-levels, system-instructions)
- Add PA memory system (decisions, preferences, projects, facts)

Cleanup:
- Remove deprecated markdown skills and workflows
- Remove crontab example (moved to workflows)

+
+# /cluster-status Command
+
+Get a quick health overview of the Raspberry Pi Kubernetes cluster.
+
+## Usage
+
+```
+/cluster-status
+/cluster-status --full    # Run complete health check workflow
+/cluster-status --quick   # Just node and pod status (faster)
+```
+
+## What It Does
+
+Invokes the `cluster-health-check` workflow to provide a comprehensive cluster health overview by coordinating specialized agents:
+
+1. **Node Health** - Node statuses, conditions, resource usage
+2. **Active Alerts** - Firing alerts from Alertmanager
+3. **ArgoCD Status** - App sync and health status
+4. **Summary** - Overall health rating and recommendations
+
+## Example Output
+
+```
+Cluster Status: Healthy
+
+Nodes:
+| Node   | Status | CPU  | Memory | Conditions |
+|--------|--------|------|--------|------------|
+| pi5-1  | Ready  | 45%  | 68%    | OK         |
+| pi5-2  | Ready  | 32%  | 52%    | OK         |
+
+Active Alerts: 0
+
+ArgoCD Apps:
+| App       | Sync     | Health    |
+|-----------|----------|-----------|
+| homepage  | Synced   | Healthy   |
+
+Recommendations: None
+```
+
+## Autonomy
+
+This command is read-only and runs without confirmation.

+
+# /deploy Command
+
+Deploy a new application or update an existing one on the Raspberry Pi Kubernetes cluster.
+
+## Usage
+
+```
+/deploy <app-name>
+/deploy <app-name> --image <image:tag>
+/deploy <app-name> --update
+```
+
+## Quick Deploy
+
+```
+/deploy myapp --image ghcr.io/user/myapp:latest --namespace apps --port 8080
+```
+
+## What It Does
+
+Invokes the `deploy-app` workflow to guide you through deploying via GitOps with ArgoCD:
+
+1. **Check existing state** - See if app exists, current status
+2. **Generate manifests** - Create deployment, service, kustomization
+3. **Create PR** - Push to GitOps repo, create PR
+4. **Sync** - After PR merge, trigger ArgoCD sync
+5. **Verify** - Confirm pods are running
+
+## Interactive Mode
+
+When run without full arguments, prompts for:
+- Application name
+- Container image
+- Namespace (default: default)
+- Ports
+- Resources (Pi-optimized defaults)
+- Pi 3 compatibility
+
+## Resource Defaults (Pi-optimized)
+
+```yaml
+requests:
+  memory: "64Mi"
+  cpu: "50m"
+limits:
+  memory: "128Mi"
+  cpu: "200m"
+```
+
+## Confirmation Points
+
+- **[CONFIRM]** Creating PR in GitOps repo
+- **[CONFIRM]** Syncing ArgoCD application
+- **[CONFIRM]** Rollback if deployment fails
