GEPA.Strategies.Acceptance behaviour (GEPA v0.3.0)

Acceptance criteria for proposed GEPA candidates.

Reflective mutations use a pluggable acceptance criterion. Merge proposals are intentionally accepted with the official merge rule: the merged program's subsample score sum must be at least the better parent sum. That rule is not user-overridable in the Python engine and is kept separate here as well.
