AWS vpc documentation change
Summary
Added example VPC configuration with route tables, updated local route documentation to include IPv6, and improved formatting
Security assessment
The changes are purely explanatory and architectural, providing implementation examples without introducing security features or addressing vulnerabilities. The IPv6 route mention is a technical detail expansion, not a security update.
