Self-hosted sandbox images

cma-sandbox carries ant 2.5.0.
These were published by hand from sandboxes-v0.1.0, so they have no GitHub build attestation.
cma-sandbox-source holds the source of the sandbox image's GPL and LGPL packages.
Install the chart with helm install cma oci://us-docker.pkg.dev/anthropic-public-registry/sandboxes/charts/cma-sandboxes --version 0.1.0 --namespace cma -f cma-values.yaml. sandboxes/kubernetes/README.md says how to write cma-values.yaml.
To pin both images, add --set image.dispatcherDigest=sha256:237ec7884552a7c077b013e489e0ffa9a2bd8b4e863c07579f722d179a052a6e --set image.sandboxDigest=sha256:d686b816635367985352f25a28801d89a1953d0b1beff347b1a6e14e77b11956.
