Go 1.25 added a new `containermaxprocs` setting that controls whether the Go
runtime will consider cgroup CPU limits when setting the default GOMAXPROCS.
The default value `containermaxprocs=1` will use cgroup limits in addition to
the total logical CPU count and CPU affinity. `containermaxprocs=0` will
disable consideration of cgroup limits. This setting only affects Linux.

- Fixed a bug where the kubelet ephemerally failed with `failed to initialize top level QOS containers: root container [kubepods] doesn't exist`, due to the cpuset cgroup being deleted on cgroup v2 with systemd cgroup manager.

- Promoted CRI communication of the cgroup driver mechanism to beta. The `KubeletCgroupDriverFromCRI` feature gate is now in beta and enabled by default. This allows the kubelet to query the container runtime using CRI to determine the mechanism for cgroup management. If the container runtime doesn't support this, the kubelet falls back to using the configuration file (you can also use the deprecated `--cgroup-driver` command line argument).

- Changed underlying logic to propagate pod-level hugepage cgroup to containers when they did not specify hugepage resources.
