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)

+# /diagnose Command
+
+Investigate and diagnose problems in the Raspberry Pi Kubernetes cluster.
+
+## Usage
+
+```
+/diagnose <issue-description>
+/diagnose pod <pod-name> -n <namespace>
+/diagnose app <argocd-app-name>
+/diagnose node <node-name>
+```
+
+## What It Does
+
+Invokes the k8s-orchestrator to coordinate multiple specialist agents for investigation. May trigger incident workflows:
+
+- `pod-crashloop` - For CrashLoopBackOff issues
+- `node-issue-response` - For node problems
+- `resource-pressure-response` - For resource alerts
+- `argocd-sync-failure` - For sync failures
+
+## Diagnosis Types
+
+### General Issue
+```
+/diagnose "my app is returning 503 errors"
+```
+
+### Pod Diagnosis
+```
+/diagnose pod myapp-7d9f8b6c5-x2k4m -n production
+```
+
+### ArgoCD App Diagnosis
+```
+/diagnose app homepage
+```
+
+### Node Diagnosis
+```
+/diagnose node pi5-1
+```
+
