Add a new `classifiers` parameter to `Eval`/`EvalAsync`/`Evaluator` that runs classification functions alongside scorers. Classifier results are recorded under a dedicated `classifications` field on `EvalResult` and logged to classifier-typed spans. Key changes: - New `Classification` and `ClassificationItem` types in `score.py` - `EvalClassifier` callable type and `OneOrMoreClassifications` union - `SpanTypeAttribute.CLASSIFIER` span type - Classifier results aggregated per-name in the root span - `scores` is now optional when `classifiers` is provided - Devserver and push CLI updated to propagate classifier metadata - Tests covering classifier-only, mixed, multi-classification, and span logging behavior
