7baa3e55 - refactor: collapse BaseRunner/BasePredictor into single class with alias

refactor: collapse BaseRunner/BasePredictor into single class with alias BaseRunner is now the single real class. BasePredictor = BaseRunner is a backwards-compatible alias. predict() is a bridge method that calls run(), eliminating duplicated setup/scope/record_metric logic. The runtime still detects which method the user overrode (run vs predict) via MRO walk and calls it directly.
