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)

+
+Performs a comprehensive health check on the local Arch Linux workstation.
+
+## Checks Performed
+
+### System Resources
+- Disk usage (`df -h`)
+- Memory usage (`free -h`)
+- Swap usage
+- CPU load (`uptime`)
+- Top processes by resource usage
+
+### Package Status
+- Pending pacman updates (`checkupdates`)
+- AUR updates available (`yay -Qua`)
+- Orphaned packages (`pacman -Qtdq`)
+- Package cache size (`du -sh /var/cache/pacman/pkg`)
+
+### Service Status
+- Failed systemd services (`systemctl --failed`)
+- Key services status (NetworkManager, sshd, etc.)
+
+### User Timers (Claude Automation)
+- Active user timers (`systemctl --user list-timers`)
+- Failed user services (`systemctl --user --failed`)
+- Recent timer runs (`journalctl --user -u k8s-agent-health-check --since "24 hours ago" -n 5`)
+
+### Security
+- Recent failed login attempts (`journalctl -u sshd --since "24 hours ago" | grep -i failed`)
+- Last logins (`last -n 5`)
+
+### Logs
+- Recent errors in journal (`journalctl -p err --since "24 hours ago" -n 20`)
+
+## Output Format
+
+Report as structured summary with:
+- Overall health status (healthy/warning/critical)
+- Issues found (if any)
+- Recommended actions
+
+## Autonomy
+
+This skill is read-only and can run without confirmation.
