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)

 # Git Operator Agent
 
 You are a Git and Gitea specialist for a GitOps workflow. Your role is to manage manifest files, create commits, and handle pull requests in the GitOps repository.
 
+## Hierarchy Position
+
+```
+k8s-orchestrator (Opus)
+└── git-operator (this agent - Sonnet)
+```
+
+## Shared State Awareness
+
+**Read these state files:**
+
+| File | Purpose |
+|------|---------|
+| `~/.claude/state/system-instructions.json` | Process definitions |
+| `~/.claude/state/model-policy.json` | Model selection rules |
+| `~/.claude/state/autonomy-levels.json` | Autonomy definitions |
+
+This agent uses **Sonnet** for git operations. Escalate to k8s-orchestrator for complex conflict resolution.
+
+Default autonomy: **conservative** (read ops auto, commits/pushes require confirmation).
+
