terminal.docker_extra_args passes flags verbatim to `docker run` (e.g.
--gpus=all, --shm-size=16g). It was wired into DEFAULT_CONFIG,
TERMINAL_CONFIG_ENV_MAP (so `hermes config set` bridged it),
terminal_tool._get_env_config (reads TERMINAL_DOCKER_EXTRA_ARGS), and
DockerEnvironment (applies extra_args) -- but it was MISSING from cli.py's
env_mappings and gateway/run.py's _terminal_env_map.
Consequence: a user who hand-edits config.yaml (rather than running
`hermes config set`) has docker_extra_args silently dropped on the CLI and
gateway/desktop startup paths, while docker_image / docker_volumes (which
ARE in those maps) bridge correctly -- producing the reported 'Hermes
partially reads the Docker config' symptom where --gpus=all and
--shm-size=16g never reach docker run.
This is the same bridge-coverage bug class that shipped before for
docker_run_as_host_user (cli + gateway) and docker_mount_cwd_to_workspace
(gateway). Fix by adding the key to both maps, plus a dedicated regression
pin in test_terminal_config_env_sync.py mirroring the existing
test_docker_*_is_bridged_everywhere guards.
