feat: install.sh auto-installs Docker when missing
- OS detection (ubuntu/debian, arch, fedora, centos/rhel) - Docker Engine: official repo (apt), pacman, or dnf - Compose plugin: docker-compose-v2, docker-compose-plugin, or CLI plugin fallback - Docker daemon auto-start via systemd/service/dockerd - User added to docker group + sg fallback for current shell - DOCKER_CMD variable handles sudo vs non-sudo transparently - Wider summary box (60 chars) for full path display
