[Tech Debt] CI/CD Deployment Automation Pipeline

[genesisgzdev]

Current State: The repository has continuous integration for security scanning (security.yml: SAST, SCA), but lacks a continuous delivery (CD) deployment flow.

Required Action: Construct a deploy.yml pipeline that:

1. Builds the Docker image leveraging Turborepo caching.
2. Pushes the image to a container registry (ECR/GCR/GHCR).
3. Automatically executes terraform plan / terraform apply.
4. Updates the Helm Chart in the production cluster.
