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)

+# Plan: Remove Redundancy + Add No-Redundancy Rule
+
+## Identified Redundancies
+
+| Item | CLAUDE.md | system-instructions.json | Action |
+|------|-----------|--------------------------|--------|
+| Conventions | Lines 63-67 | Lines 55-59 | Remove from JSON (CLAUDE.md is human reference) |
+| State file writers | Lines 23-29 table | Lines 37-42 | Keep both - different purposes (table vs structured) |
+| Key Processes | Lines 31-47 | Lines 5-34 | OK - CLAUDE.md is summary, JSON is canonical |
+
+## Changes Required
+
+### 1. Remove `conventions` from `system-instructions.json`
+
+Already documented in CLAUDE.md - no need to duplicate.
+
+### 2. Add no-redundancy principle to `CLAUDE.md`
+
+Add to Conventions section:
+```
+- **No duplication**: Information lives in one place. CLAUDE.md = overview, JSON = details
+```
+
+### 3. Add to `system-instructions.json`
+
+Add principle:
+```json
+"content-principles": {
+  "no-redundancy": "Information lives in one authoritative location",
+  "lean-files": "Keep files concise - no verbose examples or unnecessary prose"
+}
+```
+
+## Files to Modify
+
+| File | Action |
+|------|--------|
+| `~/.claude/state/system-instructions.json` | Remove conventions, add content-principles |
+| `~/.claude/CLAUDE.md` | Add no-duplication rule to conventions |
