ci_smoke: import compile_hf_bundle from its defining module

mypy resolves the package-root re-export as `object`; the canonical
import path (torchwright.compiler.hf) is what tests and examples
use.  Fixes the lint failure committed in the previous commit —
the lint invocation piped through tail and lost the exit code.
