Completion while typing not working

Beginne mit Core/Sources/KeyBindingManager/TabToAcceptSuggestion.swift, der einzigen in den Logs genannten Quelldatei, und vergleiche die gemeldeten streamChoices- und ghostText-Nachrichten mit dem Completion-Ablauf. Reproduziere das Problem mit den aufgeführten Versionen von Copilot for Xcode, Xcode und macOS; abgeschlossen bedeutet, dass während der Eingabe Completion-Vorschläge erscheinen und normal angenommen werden können.
