swarmexec v1.1.4 — agent image defaults to Docker Hub `swarmexec init` now deploys the agent from Docker Hub by default: docker.io/logleio/swarmexec-agent:latest, a public image, so init needs no `docker login`. Releases are still mirrored to the GitLab registry, and SWARMEXEC_AGENT_IMAGE / --image override the source (pin a version or use the mirror). Agent detection follows the rename: label-first (swarmexec.role=agent), with an image-name fallback that now matches both the Docker Hub name and the legacy GitLab name, so a cluster mid-migration is recognized either way. The deploy manifests carry the role label too. No API or wire-protocol change; a running agent stays compatible.
