Prefix network namespaces with wrenn-, add stale cleanup, lower diff cap

Browse Source 
Rename ns-{idx} to wrenn-ns-{idx} and veth-{idx} to wrenn-veth-{idx}
to avoid collisions with other tools. Add CleanupStaleNamespaces() at
agent startup to remove orphaned namespaces, veths, iptables rules, and
routes from a previous crash. Lower maxDiffGenerations from 10 to 8 to
prevent Go runtime memory corruption from snapshot/restore drift.
