-# duplicate_checker.py v4.0
-# Build timestamp is injected into logfile name.
-
-# --- FEATURES v4.0 ---
-# - NEU: "Kernidentitäts-Bonus": Ein hoher Bonus wird vergeben, wenn das seltenste (wichtigste) Token übereinstimmt.
-#   Dies fördert das "großzügige Matchen" auf Basis der Kernmarke (z.B. "ANDRITZ AG" vs. "ANDRITZ HYDRO").
-# - NEU: Intelligenter "Shortest Name Tie-Breaker": Wird nur noch bei sehr hohen und sehr ähnlichen Scores angewendet.
-# - Finale Kalibrierung der Score-Berechnung und Schwellenwerte für optimale Balance.
-# - Golden-Rule für exakte Matches und Interaktiver Modus beibehalten.
