Normalize agent instructions and workplan frontmatter (STATE-WP-0067)

- Align agent files with on-disk workplan prefixes (infer from workplan ids)
- Set workplan domain to registered domain_slug; add topic_slug where applicable
- Repair frontmatter delimiter formatting; migrate legacy task status literals
- Regenerate AGENTS.md, CLAUDE.md, and .claude/rules from State Hub templates

 ## Architecture
 
-kaizen-agentic has two distinct layers:
+<!-- TODO: Describe the key design decisions and component structure.
+     Key modules, data flows, external integrations, state machines, etc. -->
 
-### 1. Python framework (`src/kaizen_agentic/`)
+## Quick Reference
 
-- **`core.py`** — `Agent` (abstract base) + `AgentConfig` (dataclass). Tracks performance, supports config updates, implements kaizen interface.
-- **`optimization.py`** — `OptimizationLoop` (runs improvement cycles, detects trends, generates recommendations) + `PerformanceMetrics` (execution time, success rate, quality scores).
-- **`metrics.py`** — `MetricsStore` + `OptimizerStore` (project-scoped `.kaizen/metrics/` per ADR-004).

-### 2. Agent definitions (`agents/` — 20 files)
-
-Markdown instruction sets read and followed by Claude. Not executables. Naming convention: `agent-{name}.md`.
-Packaged copies live in `src/kaizen_agentic/data/agents/` for `pip install` distribution.

-### Custodian integration
-
-The state-hub MCP resolves the agents directory via `host_paths[hostname]` → `local_path`. Tools: `list_kaizen_agents(category?)`, `get_kaizen_agent(name)`.
