//! Unified Training Trait — re-exported from ml-core crate.
//!
//! The canonical definitions of `UnifiedTrainable`, `TrainingMetrics`,
//! `CheckpointMetadata`, and the `checkpoint` helpers now live in `ml-core`.
//! This module re-exports them so all existing `crate::training::unified_trainer::*`
//! paths continue to work.
