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.
