When CNI ADD never completes, multus DEL fails because delegate plugins
require runtime state that only exists after a successful ADD. This
creates a deadlock where containerd cannot release sandbox name
reservations, permanently blocking pod creation on the affected node.

Build a custom multus-cni image with a patch that returns success on
DEL when no cache file exists (ADD was never completed).
