refactor: complete bootstrap of ARNES agent harness framework

- Add complete agent harness structure with 8 roles (leader, triager, architect, implementer, reviewer, security, qa, documenter)
- Implement strict workflow with 9 stages and mandatory gates
- Add comprehensive verification script and runtime status tracking
- Create artifact-based evidence system with contracts and schemas
- Add agent policy matrix with permissions and anti-cheat rules
- Include test suite (44 tests passing) and CI-ready structure
- Add documentation: README, HOWTO, CHECKPOINTS, templates
- Configure model routing policies and token-aware task assignment
- Add BDD/SDD specification guides and feature templates
- Include starter pack for quick project onboarding

All verification checks pass. Framework ready for production use.

+# TEMPLATE.md — Cómo adaptar ARNES a cualquier proyecto
+
+## 1) Clonar y renombrar contexto
+- Ajusta `backlog/features.json` (`project`, `description`).
+- Crea primeras features reales en `features[]`.
+
+## 2) Reglas específicas (sin tocar core)
+- Opcional: crea `AGENTS.local.md` con reglas del dominio.
+- Opcional: crea `scripts/verify.local.sh` con checks propios del stack.
+- Mantén tickets y órdenes internas en English caveman (`harness/policies/language.md`).
+- Ajusta routing de modelos por rol/tarea en `harness/models.profiles.yml`.
+
+## 3) Flujo estándar
+1. `./scripts/start.sh` (primer uso)
+2. `python3 scripts/new_ticket.py` (leader/triager)
+3. `python3 scripts/agent_status.py show`
+4. Seleccionar 1 feature `pending` y pasarla a `in_progress`
+5. Implementar con artefactos en `work/artifacts/<feature_id>/`
+6. Cerrar solo con gates `review/security/qa` + `documenter` aprobados
+7. `python3 scripts/agent_status.py reset`
+
+## 4) Contrato de cierre
+- `status=done` exige:
+  - `reviewer.json` APPROVED
+  - `security.json` APPROVED
+  - `qa.json` APPROVED
+  - `leader-close.json` APPROVED
+  - `./scripts/verify.sh` OK
+
+## 5) Principio de template
+- El core ARNES es agnóstico.
+- Todo lo específico de proyecto vive en overlays (`AGENTS.local.md`, `verify.local.sh`, docs propias).
