Subject: [PATCH] feat(bridge): Bilder >2MB serverseitig auf 1568px verkleinern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Claude-Vision-API hat ~5MB Base64-Limit. Stefan's 4MB Foto via
Buroklammer (DocumentPicker) sprengte das, Claude lieferte leere
Antwort zurueck. Galerie-Pfad ging weil react-native-image-picker
schon clientseitig komprimiert.

Bridge resized jetzt JPEG/PNG/WebP/GIF >2MB auf max 1568px lange
Seite (Anthropic-Empfehlung), JPEG q=85. SVG, PDF, ZIP, Office-Docs
bleiben unangetastet — die laufen ueber Tools, nicht Vision.
