Verweis statt Nacherzaehlung: die Engine stempelt den Ursprung (#697, #677)

- Werkzeugkontext kennt Lauf und Aufgabe des Laufs (RunId, RunTaskId); die Delegationskette traegt den Lauf des Aufrufers weiter (RunId, CallerRunId) - Aufgaben tragen origin_run / origin_task (Datei, DB, Taskboard "Arose from"), gestempelt, nie vom Agenten behauptet - Kommentare nennen den Lauf, in dem sie geschrieben wurden - Laufbeleg: CallerRunId; Laufansicht fuehrt zu "Delegiert von" und "Delegiert an" - #677: task_update ersetzt den Rumpf nicht mehr, Abnahmekriterien aendert nur der Ersteller; Kommentare der Fremdinhalt-Stufe auf fremden Aufgaben kommen gerahmt an - WebUI: Herkunft auf der Aufgabenkarte mit Link zum Lauf Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
