Downsize GNN hidden channels/heads (128→64, 16→4) to match the 30-stock
price-only universe before alternative data processors are ready.
Add USE_ALTERNATIVE_DATA flag (default False) that skips news/social
branches so the model trains on real data rather than zero-filled stubs.
Standardize target returns per-batch in the data pipeline to stabilize
training.
Introduce walk-forward cross-validation with expanding windows:
configurable fold count and out-of-sample years.
Add IC loss weighting (0.7) to complement MSE, and wire it into the
trainer alongside the new loss function.
