Implementation Plan: Shared PVC Workspace & Git Clone

Objective

Implement a shared Persistent Volume Claim (PVC) strategy to ensure the repository is only cloned once and all parallel scanners can access the same codebase without re-downloading it.

Requirements

• Use Argo Workflows volumeClaimTemplates to define a temporary PVC for the workflow duration.
• Create a clone-repo task in the DAG.
• The clone-repo task should use a standard git image (e.g., Alpine/Git) to clone the repo-url at git-revision into the shared PVC mounted at /workspace.
• Ensure all subsequent tasks will mount this PVC at /workspace.

Agent Instructions

1. Modify the ClusterWorkflowTemplate to add the volumeClaimTemplates.
2. Add the clone-repo task template that executes git clone.
3. Configure the DAG so the parallel scanning steps depend on the successful completion of clone-repo.
