The image's default s6 entrypoint launches the interactive TUI, which exits
without a TTY and crash-loops the container. Override the entrypoint to run
'hermes gateway run --force' (the documented Docker mode) and point HERMES_HOME
at the mounted data dir so the Signal platform config + state persist. The
Signal platform is enabled in config.yaml (platforms.signal.enabled).
