_No response_

### Anything else?

VS Code Version: 1.116.0
OS: macOS 26.4.1 Tahoe ARM64

Start with .devcontainer/devcontainer.json and reproduce the onCreateCommand failure by opening the repository in VS Code on macOS ARM64. Trace the /bin/sh -c dotnet restore step and the missing libhostpolicy.so error; done means the DevContainer starts successfully and restore completes.
