• SqlCopilotCommon reference was removed from this project, but bin/ref/SqlCopilotCommon.dll is still being added/updated in this PR and appears to be unreferenced by any .csproj in the repo. If it’s no longer needed, please remove the binary to avoid carrying unused artifacts; if it is required at build/runtime, add an explicit reference/copy step so the dependency is discoverable and consistent.
