The unit comment always claimed the webui drives the same agent state as
the gateway, but the image bakes HERMES_HOME=/opt/data and no unit
overrode it. Podman auto-creates a fresh anonymous volume at every
image-VOLUME point on container recreation, so each restart reset the
webui's config home to the image-default template (provider: auto ->
openrouter.ai with no API key), while the gateway read the corrected
/data/config.yaml. Pin HERMES_HOME=/data so both processes share one
config/state root and config edits propagate without a recreate.
