CLAUDE: publish_libtorch_mirror.sh - libtorch -> mirror maven layout (piece 4B)

Server-side copies the already-uploaded libtorch zip into
mirror.elphel.com/maven-dependencies/org/pytorch/libtorch-cxx11-cu128/2.7.1/ (maven
layout: .zip + .pom + .sha1/.md5, no 3.8GB re-upload) so imagej-elphel's -Plibtorch
profile can dependency:unpack it. Pairs with fetch_libtorch.sh (direct download).
