Run the guest CLI via buildGuestCommand() over the VM's SSH channel.
Default timeout 30s. Never rejects on non-zero exit; check success.
When running in a VM, returns the paths of binaries inside the guest.
When running in a VM, returns the VM for raw exec (e.g. background agent start/stop).
Runs the guest CLI inside a VirtualMachine via SSH.
