- add entrypoint.sh to run as PUID/PGID via su-exec, set UMASK, copy config.yml.sample into /config atomically, and fix ownership - update Dockerfile to set QBM_DOCKER, PUID/PGID/UMASK defaults, install su-exec, and use tini + entrypoint - add util.in_docker() and use it to auto-detect container runtime - adjust default config dir fallback to prefer /config when sample YAML exists - improve version banner to indicate Docker runtime
