evo2 recipe: drop empty src/evo2_sae package

The recipe currently has no model-specific Python module — the extractor
is upstream (`predict_evo2`) and the two scripts are simple CLIs in
scripts/. Drop the empty package and adjust pyproject.toml so setuptools
doesn't try to discover anything. Will reintroduce when there's actual
library code to put there (eval, dashboard, dataloaders).
