Description: This PR extends and refactors the ALICE3 TRK Vertex Detector (IRIS) geometry with the following updates: Pure cylindrical IRIS option • Adds support for a fully cylindrical IRIS geometry (no φ gaps). • Barrel layers, disks, cold plate, services, and mechanical walls correctly span 360° in φ. • Mechanical walls now consistently close the petal/case in Z. • Cutout construction works for both multi-petal and single-cylinder layouts. Sensitive vs non-sensitive silicon split • VD silicon is split into 20 µm sensitive and 80 µm non-sensitive layers, improving material realism while keeping sensitive-volume handling unchanged. Updated default geometry • The v3 IRIS geometry is now built by default; previous layouts remain available. Geometry and detector integration cleanup • More consistent φ-span handling and wall construction. • Dynamic VD sensor registration (no hard-coded counts), with unchanged Detector.cxx logic.
