Some guests ignore CtrlAltDel long enough that vm stop sat in wait_for_exit until the client disconnected, leaving the daemon to report context canceled instead of actually stopping the VM.
Keep the graceful shutdown attempt, but treat a grace-window timeout as a fallback case: log the timeout stage and continue into the existing forced cleanup path instead of returning immediately. Add a fake Firecracker API/process regression that exercises the timeout-to-cleanup transition.
Validate with go test ./..., make build, and a live ./banger vm stop ea run that now completes instead of hanging.
