Neue Cloud Function diagnosePlant: Foto + optionale Art an Claude, deutsches JSON-Ergebnis (Befund/Ursache/Behandlung/Vorbeugung). App: PlantDiagnosisService + Untersuchen-Sektion im Pflanzen-Detail mit Ergebnis-Bottom-Sheet und KI-Disclaimer. askClaude max_tokens 1024→2048 (adaptives Denken zählt mit ins Limit). Deploy steht aus. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
