Commit Message

Warn when optuna study direction mismatches PEC direction

When an optuna Study is passed as the PECOptimizationFunction method, the
study's optimization direction is fixed at creation time and used as-is
(the study is not recreated). A mismatch with the direction PEC expects
silently optimizes the wrong way -- e.g. data fitting does maximum
likelihood estimation and requires direction='maximize'. Warn in that
case so the misconfiguration is visible.

Also fix the adjacent optuna_kwargs check: _optuna_kwargs is always a dict
(never None), so the "ignored" warning previously fired even when no
kwargs were passed; use a truthy check instead.
