CFAT Cloud Foundations Assessment Integration
Integrates Cloud Foundation Assessment Tool (CFAT) JavaScript engine with runbooks

This module provides dual-engine assessment capability:
- Python-based assessment (existing runbooks CFAT)
- JavaScript-based assessment (cloud-foundations-templates CFAT)
- Unified reporting with project management integration
- CloudShell compatibility for enterprise environments

Strategic Alignment:
- Enhances existing src/runbooks/cfat/ capabilities without duplication
- Maintains Rich CLI standards and enterprise quality
- Provides executive reporting with business value quantification
