Test never interrupts an active rollout
The image changes while the controller is already stopped, so restart simply begins a new rollout.

I'm wondering if we should pause the pool at this stage. I'm afraid that if the pulling is fast enough, the node might go in rebooting before scale down the controller, and it is a possible source for race conditions. Would it make sense to pause it when we detect the staging, scale down the operator and unpause it?

Summary
Context
Part of the e2e test planning in #69 (scenario 5: kill controller/daemon during rollout).
Manual testing also revealed that scenarios 4 (faulty node after reboot) and 8 (cross-distro bad image) both fail — the controller has no reboot timeout and doesn't correlate Node.Ready status, so nodes stuck after reboot are never marked degraded. Those need feature work before tests can be written.
