+ *
+ * Traegt das Feld "name_from_filename" in eine bestehende buyers_vision.json
+ * nach, OHNE die Vision-Ergebnisse anzufassen und OHNE GPU/Neuverarbeitung.
+ * Nutzt exakt dieselbe Logik wie der vision_runner, damit die Werte
+ * identisch zu kuenftigen Laeufen sind.
+ *
+ * Aufruf:
+ *   npx tsx add_name_from_filename.ts out_Z/buyers_vision.json
+ *   npx tsx add_name_from_filename.ts out_Z/buyers_vision.json --overwrite
+ *
+ * Ohne --overwrite werden nur Datensaetze ergaenzt, die das Feld noch nicht
+ * (oder null) haben. Ein Backup .bak wird immer angelegt.
