This change adds the git_commit_sha as metadata to all Nomad jobs deployed via Terraform. The commit SHA is passed from GitHub Actions workflows through Terraform variables down to the Nomad job specifications. Changes: - Updated deploy-infra.yml and deploy-job.yml workflows to export GIT_COMMIT_SHA - Added git_commit_sha to Makefile tf_vars - Added git_commit_sha variable to provider-gcp and nomad module variables - Added meta block with git_commit_sha to all Nomad job HCL files - Updated all module calls to pass git_commit_sha through This enables tracking which git commit is currently deployed for each Nomad job.

Make git_commit_sha required in all job modules to catch missing pass-throughs at plan time. The root provider-gcp/variables.tf still has a default for when the env var isn't set during local development.
Uses `git rev-parse --short HEAD` as the default value for GIT_COMMIT_SHA if not explicitly set via environment variable. Falls back to 'unknown' if not in a git repository.

wouldn't this be annoying for dev where you rebuild just one job, but then run make plan ; make apply?

would it be possible to set up terraform to ignore_changes for this somehow?
