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.
