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

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.
