llmp2p container image v0.3.2

Multi-arch (linux/amd64 + linux/arm64) FROM scratch image built from the
pinned v0.3.2 release source, keyless cosign-signed by this pipeline.
Registry: registry.gitlab.com/6admin.io/docker/llmp2p/llmp2p:v0.3.2

Tag moved to this commit during registry recovery: the previous tag
target (README-only commit) had no container image and the registry
repository was purged when the old same-path project's cleanup ran; the
image content is byte-identical (deterministic build from the same
pinned source).
