oa::ml::training::Validation

Runs application-owned inference validation at completed lifecycle boundaries. Epoch-based training evaluates once at every epoch end. Step-only training evaluates at each non-zero configured interval and once at train end when the final step was not already evaluated. Evaluation wall time is excluded from training throughput and the callback never submits work on its own.
