- Use Docker instead of buildah in composite action
- Build workflows now run on docker-builder label
- Add actionlint config for custom runner labels
- Avoids nested containerization complexity in k8s

## Summary
- Fix workflow to use `github.*` context variables (Forgejo schema validator only recognizes GitHub Actions syntax, not `gitea.*` aliases)
- Pass untrusted inputs through environment variables (security best practice per actionlint)
- Add actionlint to Brewfile and pre-commit config to catch workflow validation errors locally
## Deployment and Testing
- [x] Pre-commit hooks all pass
- [x] actionlint validates `.forgejo/workflows/test.yaml` successfully
- [ ] Verify workflow runs without errors on Forge after merge
