Report which dragonfruit-cli is in use and the print formats it can write.

Find islands: regions that appear in a layer with nothing solid beneath them.

These are where a resin print needs supports. The model is scanned as it sits in the STL: layer 0 is its lowest point, as if lying on the plate, and no supports are considered. Positions are in the STL's own X/Y/Z (mm). Layers are sliced layer_height apart on a px_mm grid; a region counts as supported if solid lies within support_buffer_mm of it in the layer below. Detections that start within cluster_mm (XY distance from the cluster's first detection) and ten layers of each other are merged into one entry; 0 disables that. Entries whose first_area_mm2 is under min_area_mm2 are then dropped, and the max_islands largest by that area are returned, with truncated set if there were more.

Report an STL's triangle count, bounding box, size (mm) and volume (mm3 and ml).

Warns about sizes that suggest the wrong units and volumes that suggest the mesh is not a closed solid. Volume is the CLI's signed-volume sum, which cannot tell a closed mesh from an open one that happens to integrate sensibly; it does not report watertightness itself. The absence of the fill-ratio warning therefore proves nothing about whether the mesh is closed.
