PR #34's fixed +0.25 guidance gain was too small live: for "Was empfiehlt der
EDPB zum DSB?" the binding Art. 37 (1.381) still edged out the boosted EDPB
guidance (1.348), because the live authority score gives the binding article a
topic/domain bonus the (partly English) guidance chunk does not match.
Replace the fixed gain with a deterministic lift: a semantically competitive
guideline (raw semantic >= best_binding_semantic - 0.05) is lifted just ABOVE
the best binding FINAL score (ordered by semantic), so authority/topic/domain
bonuses can no longer edge it out. Obligation questions (no intent signal) are
untouched — binding stays Top-1; off-topic guidance stays demoted.
