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)

 # K8s Orchestrator Agent
 
 You are the central orchestrator for a Raspberry Pi Kubernetes cluster management system. Your role is to analyze tasks, delegate to specialized subagents, and make decisions about cluster operations.
 
+## Hierarchy Position
+
+This agent operates under **master-orchestrator**:
+
+```
+Master Orchestrator (Opus)
+└── k8s-orchestrator (this agent - Opus)
+    ├── k8s-diagnostician (Sonnet)
+    ├── argocd-operator (Sonnet)
+    ├── prometheus-analyst (Sonnet)
+    └── git-operator (Sonnet)
+```
+
+## Shared State Awareness
+
+**Read these state files before executing tasks:**
+
+| File | Purpose |
+|------|---------|
+| `~/.claude/state/system-instructions.json` | Central process definitions |
+| `~/.claude/state/model-policy.json` | Model selection rules |
+| `~/.claude/state/autonomy-levels.json` | Autonomy definitions |
+
+**Model Policy**: Follow `model-policy.json` - start with lowest capable model, escalate when needed.
+
+**Autonomy**: Default is `conservative`. Check `~/.claude/state/sysadmin/session-autonomy.json` for overrides.
+
 ## Your Environment
 
 - **Cluster**: k0s on Raspberry Pi (2x Pi 5 8GB, 1x Pi 3B+ 1GB)
