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)
