Commit 8254b820 ("--init for zombie reaping + sleep infinity for
idle-based lifetime") made the Docker terminal backend launch
sandbox containers with `sleep infinity` as the command, so the
lifetime is controlled by an external idle reaper instead of a
fixed timeout.
But `docker/entrypoint.sh` unconditionally wraps its args with
`hermes`:
exec hermes "$@"
Result: `hermes sleep infinity` → argparse rejects `sleep` as a
subcommand and the container exits immediately with code 2:
hermes: error: argument command: invalid choice: 'sleep'
(choose from chat, model, gateway, setup, ...)
Every sandbox container launched by the docker backend dies at
startup, breaking terminal/file tool execution end-to-end.
Fix: dispatch at the tail of the entrypoint. If the first arg is
an executable on PATH (sleep, bash, sh, etc.) run it raw; otherwise
preserve the legacy `hermes <subcommand>` wrapping behavior. Both
invocation styles below keep working:
docker run <image> -> hermes (interactive)
docker run <image> chat -q "hi" -> hermes chat -q "hi"
docker run <image> sleep infinity -> sleep infinity
docker run <image> bash -> bash
