[asrar-mared]

This pull request introduces the ZAYED‑SHIELD GHSA Remediation Engine v1.0.0
into the GHSA‑856v‑8qm2‑9wjv branch. This engine provides an enterprise‑grade
automated framework for scanning, planning, executing, and reporting on GHSA
advisory remediation at scale.

Included:

• ZAYED‑SHIELD GHSA Remediation Engine (scanner → planner → executor → reporter)
• Strategic enterprise positioning document
• Full methodology and architecture for large-scale advisory remediation

This establishes the foundation for automated, auditable, and scalable
security advisory processing.

automation foundation inside the GHSA workflow.
