          Runner Re-registration Required
          ========================================
          
          The runner needs to be re-registered with the correct Gitea instance URL.
          
          Steps to re-register:
          
          1. Get a new registration token from Gitea:
             {{ gitea_instance_url }}/admin/actions/runners
             Click "Create New Runner" and copy the token
          
          2. Update .env file with the token:
             GITEA_RUNNER_REGISTRATION_TOKEN=<your-token>
          
          3. Re-register the runner:
             cd {{ gitea_runner_path }}
             ./register.sh
          
          Or use Ansible to set the token and register:
          ansible-playbook -i inventory/production.yml \
            playbooks/register-gitea-runner.yml \
            -e "runner_registration_token=<your-token>"
          
          ========================================
