Add a dataset

Make a new candidate pool available to ALF by subclassing BaseDataset. The dataset supplies the candidate pool, its labels, train/validation splits, and a query interface, so it can serve both the search space and (in offline mode) the Oracle.

Base class: BaseDataset. Key methods: load_dataset, query.

Steps

1. Subclass BaseDataset under tools/alf_tools/datasets/.

2. Implement load_dataset (build the candidate pool and labels) and query.

3. Pick a compatible modality (e.g. protein sequence or SMILES) so models line up.

4. Add tests and run the build / pre-commit checks.
