fix: update Dockerfile.opencode CMD + add opencode to CI matrix and Helm chart

- Fix CMD to use 'run' subcommand (matches #335 fix for other Dockerfiles)
- Add opencode variant to build.yml (build-image, merge-manifests, promote-stable)
- Add opencode to docker-smoke-test.yml
- Add commented-out opencode preset example in Helm values.yaml
