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

Browse Source 
- 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
