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)

+description: Invoke the programmer agent for code development tasks
+aliases: [code, dev]

+---
+
+Routes programming tasks to the programmer-orchestrator agent.
+
+## Usage
+
+```
+/programmer <task description>
+/code <task description>
+/dev <task description>
+```
+
+## Examples
+
+```
+/programmer add user authentication to the API
+/code fix the bug in the payment processing
+/dev refactor the database connection pooling
+```
+
+## Workflow
+
+The programmer-orchestrator follows this workflow:
+
+1. **Plan** - code-planner explores and designs solution
+2. **Approve** - User reviews and approves the plan
+3. **Implement** - code-implementer writes the code
+4. **Review** - code-reviewer checks quality
+5. **Commit** - Orchestrator commits approved changes
