feat(01-03): deploy paperforge_lite package through setup wizard

- setup_wizard.py now copies the paperforge_lite/ package alongside
  the worker and ld_deep scripts during deployment
- Two copy targets: <pf_path>/worker/paperforge_lite/ for
  literature_pipeline.py and <skill_dir>/literature-qa/paperforge_lite/
  for ld_deep.py
- Existing copy targets for literature_pipeline.py and ld_deep.py
  remain unchanged
- Warning emitted if paperforge_lite source not found
