feat: Add complete DevOps infrastructure with ArgoCD GitOps

- Add ArgoCD Helm deployment via Terraform (argocd.tf)
- Update Terraform providers to use kubectl config authentication
- Enhance main.tf with improved cluster and resource management
- Add ArgoCD application manifest for GitOps deployment
- Update CI/CD pipeline with Docker Hub integration
- Improve .gitignore to exclude ArgoCD CLI binaries while preserving configs

This commit establishes a complete DevOps infrastructure with:
- Minikube cluster automation
- ArgoCD for GitOps deployments
- CI/CD pipeline with Docker Hub integration
- Infrastructure as Code with Terraform
