Fünfter und letzter Durchgang der part/part-of-Aufteilung - reine Verschiebung, keine Logikänderung. chat_view.dart schrumpft von 2116 auf 33 Zeilen (nur noch Bibliothekskopf). Verifiziert per automatisiertem Blockvergleich gegen das Original und flutter analyze. Damit sind alle 5 in der M2-Ist-Analyse gefundenen Gott-Dateien aufgeteilt; ROADMAP-Punkt "Toten Code & Duplikate entfernen, Ordnerstruktur vereinheitlichen" abgehakt.
