Reusable Gitea Actions workflows for lint, test, build, and deploy:
- lint-python, lint-node, lint-rust
- test-python, test-node, test-rust
- build-push (Docker build + push to Gitea registry)
- deploy-k8s (GitOps image tag update in cluster repo)
Plus example caller workflows for python-fullstack, rust-service,
and node-frontend stacks. Branch refs aligned to staging per CON-570 standards.
