Complete Pipeline Fix - PEP 668 + OIDC + Caching

🎉 Complete Pipeline Fix

This release includes all fixes needed for a successful GitHub Actions + OIDC + CodeBuild deployment:

✅ Fixed Issues

1. PEP 668 - Externally Managed Environment (Primary Issue)

• Added --break-system-packages flag to pip install in Dockerfile
• Resolves Python 3.11+ (Debian Bookworm) package installation restrictions
• Allows Lambda Runtime Interface Client installation

2. OIDC Authentication

• Added missing IAM permissions for OIDC provider management
• iam:UpdateOpenIDConnectProviderThumbprint
• iam:CreateOpenIDConnectProvider, DeleteOpenIDConnectProvider
• iam:GetOpenIDConnectProvider, ListOpenIDConnectProviders

3. Dynamic Repository Detection

• Repository and organization names auto-detected from GitHub context
• OIDC trust policies use dynamic values
• Infrastructure portable for forkers

4. Base Image Caching (Re-enabled)

• Simplified Docker manifest parsing logic
• Non-blocking graceful error handling
• Caches Debian base to private ECR for faster builds

🚀 Expected Behavior

Complete GitHub Actions workflow should now:

1. ✅ Authenticate via OIDC (passwordless)
2. ✅ Deploy infrastructure with dynamic detection
3. ✅ Build Docker image with pip packages
4. ✅ Cache base images to private ECR
5. ✅ Deploy Lambda function successfully

📦 Technical Details

• Fixed: Docker build failing at pip install phase
• Fixed: OIDC provider thumbprint update permission errors
• Fixed: Dynamic repository/org detection for portable infrastructure
• Improved: Base image caching with better error handling
