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)

+# Handoff: Linux Sysadmin Agent Implementation
+
+## Context
+Brainstorming session completed for building a Linux sysadmin AI agent.
+
+## Plan Location
+`/home/will/.claude/plans/shimmering-discovering-bonbon.md`
+
+## What Was Decided
+
+### Architecture
+- Multi-agent system with **master-orchestrator** (Opus) overseeing all agents
+- New **linux-sysadmin** agent (Sonnet) for Arch Linux workstation
+- Existing K8s agents become managed by master-orchestrator
+- Shared state files in `~/.claude/state/` for cross-agent awareness
+
+### Linux Sysadmin Agent
+- **Target**: Arch Linux with pacman/yay/homebrew
+- **Scope**: Full sysadmin (maintenance, troubleshooting, config, security)
+- **Autonomy**: Conservative by default (confirm all changes), session-configurable
+- **Interaction**: CLI + scheduled, alerting deferred
+
+### Key Design Decisions
+- Claude Code compatible (Markdown + YAML frontmatter for agents)
+- JSON files for state/data (not agent definitions)
+- Model selection policy for cost efficiency (haiku → sonnet → opus)
+- Agents can delegate to multiple subagents (parallel/sequential)
+- `system-instructions.json` captures all processes
+- `future-considerations.json` tracks deferred items (all agents aware)
+
+### Settings.json Cleanup Required
+- Remove non-standard `agents` field with `promptFile` entries
+- Keep only standard Claude Code settings
+
+## Implementation Order (20 steps, 7 phases)
+1. Foundation (state files, CLAUDE.md)
+2. Master orchestrator agent
+3. Linux sysadmin agent
+4. Update existing K8s agents
+5. Clean settings.json
+6. Skills & slash commands
+7. Workflows
+
+## Future Considerations to Track
+- Prometheus/Alertmanager for workstation alerting
+- Network admin agent
+- Personal assistant agent
+- External LLM integration
+- Slash commands redesign
+
+## Next Action
+Read the full plan and begin Phase 1: Foundation
