Add raw_6000bp_n1000 (1000 × 6000bp random)

clean: strip multigpu smoke entries from README

clean: drop smoke ntv3_8m_smoke_multigpu* configs (parquet)

smoke (accelerate 8xH100): fresh path multi-rank join

smoke (accelerate 8xH100): multi-rank coordination

smoke (accelerate): single-rank verify

smoke (duckdb): ArielPorath dataset

smoke (simplified): single-pass map

fix: add fold_* features to dataset_info.raw to match parquet

clean: drop stale configs from README; mark raw as default

clean: drop stale folds + ntv3_8m_smoke configs (old schema)

smoke (new flow): 8M embeddings unified config

smoke (new schema): raw + fold_* cols

smoke: ntv3_8m_smoke embeddings

smoke: 4-fold CV

smoke: raw 100 seqs

smoke: folds

smoke: raw
