Before this commit, we held onto *cobra.Command objects,
but that is not actually supported: after the first Execute(),
commands like updateCmd are stuck on the first-ever provided ctx.

For gok vm run, this means an explicit -arch=amd64 or -arch=arm64
might become necessary. In general, I recommend configuring
GOOS and GOARCH in config.json explicitly:
