make push builds linux/amd64 and linux/arm64 natively, each on a daemon
of that arch (amd64 on fsn1app1 via DOCKER_HOST, arm64 locally), pushes
the per-arch tags, and joins them into the dated and latest manifest
lists with docker buildx imagetools, mirroring the baseimage repo.
Pin the docker:cli source to 29.9.3 plus its manifest list digest, tag
the image as git.eeqj.de/sneak/ipabusedb-docker-reporter with the date
and latest, add a push target, and rename the remaining
ipabusedb-docker-ssh references in the README and package doc.
Build on git.eeqj.de/sneak/baseimage:2026-11-05 with the docker CLI
copied from docker:cli. A runit service sleeps INTERVAL seconds
(default 1200), then runs the reporter with --since INTERVAL --submit;
DOCKER_CONTAINER_NAME and IPABUSEDB_API_KEY come from the container
environment. Add .dockerignore, make image, and README section; fix the
binary name in .gitignore.
