SDK release for OpenShell core v0.1.8.

Changes since v0.1.7

• Go 1.26 or later is now required. The dependency updates to golang.org/x/* and grpc v1.85.0 need Go 1.26, so go.mod now says go 1.26.0 (#14, #32).
• Bindings regenerated from core v0.1.8 (#21, #33). See the core changes.

Matches OpenShell core v0.1.8.

The first release of the Go SDK as a standalone module at github.com/ai-openshell/sdk-go. It was github.com/NVIDIA/OpenShell/sdk/go before; packages and APIs are unchanged, and the bindings are generated from OpenShell core v0.1.7. SDK releases follow core releases, so SDK vX.Y.Z works with core vX.Y.Z.

Breaking change for consumers

The import path changes. Consumers rewrite their imports and fetch the new module:

grep -rl --include='*.go' --include=go.mod 'github.com/NVIDIA/OpenShell/sdk/go' . | xargs perl -pi -e 's#github.com/NVIDIA/OpenShell/sdk/go#github.com/ai-openshell/sdk-go#g'
go get github.com/ai-openshell/sdk-go@latest && go mod tidy
