Roland Tannous 737017a511 fix(studio): lazy-import extract_model_size_b in llama_cpp to fix transformers 5.x version switch 
PR #4769 (e4d14992) added a module-level `from utils.models import
extract_model_size_b` to llama_cpp.py.  Since core/inference/__init__.py
eagerly imports llama_cpp, the spawn subprocess now hits:

  core.inference.__init__  →  llama_cpp  →  utils.models  →
  model_config (line 8: `from transformers import AutoConfig`)

…before _activate_transformers_version() has a chance to prepend
.venv_t5/ to sys.path.  Python caches transformers 4.57.6 in
sys.modules, and no subsequent sys.path change can override it.

Fix: replace the eager import with a thin wrapper that defers the
import to first call.  This breaks the transitive chain so
transformers is not loaded until after version activation.
