Gateway container image 0.0.21 has exec format error

[harinish45]

Issue Description

The OpenShell gateway container image ghcr.io/nvidia/openshell/cluster:0.0.21 fails to start with an exec format error:

exec /usr/local/bin/cluster-entrypoint.sh: exec format error

Steps to Reproduce

1. Install OpenShell CLI v0.0.21
2. Run openshell gateway start --name test
3. Gateway fails to start with exec format error

Investigation

• The error occurs even with /bin/sh entrypoint override
• Image architecture is amd64/linux (correct for x86_64 WSL2)
• The dev image works correctly: docker run --rm --entrypoint /bin/sh ghcr.io/nvidia/openshell/cluster:dev -c 'echo test' outputs test
• Only the 0.0.21 tagged image is broken

Environment

• OpenShell CLI version: 0.0.21
• Docker Desktop 4.67.0 on WSL2 (Ubuntu)
• Architecture: x86_64

Workaround

Using the dev image tag works, but the CLI is hardcoded to use 0.0.21.

Request

Please rebuild or fix the 0.0.21 image tag, or release a new version with a working image.

We haven't seen this happening. But 0.0.22 is out, can you try that and open a new issue if you still see it happening?
