feat(ci,iac): Consolidate Forgejo CI workflows and add Talos Terraform IaC
Consolidate three separate Forgejo Actions (argocd-sync, security-scan, validate-k8s) into single cluster-ci workflow for cleaner CI/CD pipeline with proper job sequencing and reduced auth overhead. Add Terraform configuration for Talos cluster machine configs: - Provider setup for Talos - Centralized variables for CP and worker configs - Template-based config generation for controlplane.yaml and worker-*.yaml - Sensitive data separated in terraform.tfvars (gitignored) - Local state tracking for infrastructure
