GitHub Action: Auto-Post Architecture Diagrams on IaC PRs

Short summary

InfraSketch GitHub Action automatically generates architecture diagrams for Infrastructure-as-Code pull requests, supporting Terraform, Kubernetes, Bicep, CloudFormation, and Docker Compose. The action posts clickable diagram links as PR comments with no setup beyond a workflow file, no secrets required, and uses static analysis. Unlike paid alternatives (Pluralith $250/mo, Holori), this action requires no account or cloud credentials.
