"""`hermes debug` must report the EFFECTIVE terminal backend.
``terminal.backend`` in config.yaml is bridged to the ``TERMINAL_ENV`` env var,
but a ``TERMINAL_ENV`` set in .env / the shell overrides config and is what
``terminal_tool`` actually uses. The dump used to print only the config value,
which hid the override and made users believe the agent was running ``local``
while it was really jailed in a docker/podman sandbox (and vice-versa).
