cAdvisor v0.57.0 adds container_creation_time_seconds metric, exposes cgroup v2 memory.events as Prometheus metrics, and supports Podman's new JSON files.

Why it matters: Monitor the new container_creation_time_seconds metric to assess pod startup latency; enable cgroup v2 memory.events collection for enhanced OOM detection.
