Fix: Region-BBox aus VLM-Analyse + generische Tags filtern
Wenn keine Viewport-BBox gesetzt ist, nutzt der Query-Generator die VLM-Regionsschaetzung (z.B. Europa, Naher Osten) als grobe BBox. 70+ Regionen gemappt (DE/EN). Generische OSM-Tags (building, highway, landuse) werden gefiltert um Overpass-Timeouts zu vermeiden. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
