Function expandDefaultToolset

pkg/workflow/mcp_github_config.go:213–251

expandDefaultToolset expands "default" and "action-friendly" keywords to individual toolsets. This ensures that "default" and "action-friendly" in the source expand to action-friendly toolsets (excluding "users" which GitHub Actions tokens don't support).
