I was having issues running nerdbox on macos with nerdctl and couldn't find a root cause until I increased the log level:

[2025-11-17T23:27:50Z WARN  devices::virtio::vsock::muxer_thread] Failed to create listening proxy at "../../../../../../../var/run/containerd/io.containerd.runtime.v2.task/default/ad8b7eb45b55b08b8732715f51a440aa0505f371033c778c99bcd98984599107/vm/run_vminitd.sock": CreatingSocket(ENAMETOOLONG)

This PR sets the log level to warn by default.

The previous level was labeled as debug, but it was actually setting error. libkrun's debug log level is a lot, so I don't think it would be useful to enable by default.

This will surface errors such as UDS<->vsock proxy bind issues which
can happen if the socket paths are too long.
