- Prepare() uses SwapNodePool + SwapDaemonSet from spec.resources - Cleanup() is empty - PKB framework auto-deletes spec.resources - All _pod_exec(pod, ...) calls replaced with daemonset.PodExec(...) - DaemonSet: remove workload tools; separate PKB pods (r3457826290) - Remove cgroup v2 unlock hack (r3457928855) - Pre-fetch kernel source for Phase 3b - Fix COS_CONTAINERD -> UBUNTU_CONTAINERD (r3472549985)
Inherits PR1 framework changes (swap_config as NodepoolSpec field). - Prepare(): deploy SwapDaemonSet + _delete_default_pool(cluster) - Phase 2: stress-ng vmstat/pidstat sampling (kswapd/kcryptd CPU%) - DaemonSet: adds stress-ng + build tools, pre-fetches kernel source

feat(swap_encryption/pr4): Phase 2 — CPU overhead and I/O interference under swap pressure
Stacked PR 4/5. Inherits PR1 framework (swap_config as NodepoolSpec field).
Benchmark nodepool provisioned automatically by GKE cluster creation.
Phase 2 additions:
