v2.5.1 — Chat-Verlauf bleibt beim Reload erhalten

- loadHistory() leert Chat nicht mehr (chat.innerHTML = '' entfernt)
- Nur fehlende Nachrichten werden angehängt, bestehende bleiben
- Cookie mit path=/ für konsistente Session über alle Routen
- cowboy shot statt upper body (besserer Danbooru-Tag für NoobAI-XL)
- very aesthetic, absurdres als Quality-Tags
