Support HCL Ecosystem Code Indexing (Terraform, OpenTofu)

Problem to Solve

HCL (HashiCorp Configuration Language) and Terraform/OpenTofu are essential for Infrastructure as Code (IaC) across organizations. They are widely used for cloud infrastructure provisioning, configuration management, and deployment automation on AWS, Azure, GCP, and other cloud providers. Currently, the Knowledge Graph lacks HCL/Terraform support, limiting code intelligence features for infrastructure engineers and DevOps teams.

Proposed Solution

Implement an HCL/Terraform parser that extracts code entities (resources, data sources, modules, variables, outputs) and their relationships (dependencies, module calls, variable references) so the Knowledge Graph can index and search infrastructure code intelligently.
