Live-Streaming im Chat — Text erscheint Wort für Wort

- events.ts: Leere Streaming-Nachricht bei agent-started anlegen,
  claude-text Events schreiben direkt in die aktuelle Nachricht
- ChatPanel: Typing-Dots nur bei leerer/fehlender Streaming-Nachricht
- Kein Warten auf agent-stopped mehr — Text erscheint sofort
