 * handles the input, `continueExitCode` returns pass-through, and any other
 * non-zero exit code surfaces an error and handles the input so the failed
 * command is not forwarded to the model. The recursion
 * guard prevents extension-originated or nested dispatch from re-entering the
 * bridge while the child command runs.
