v0.2.0

Add extractPreviews() to enumerate every preview in a file (Bambu 3MF plates, DWF sheets, OLE streams, SketchUp scenes); extractPreview() still returns the default pick. New Preview.name field.

v0.1.2

Add Bambu Studio 3MF (Metadata/plate_N.png) preview support.

v0.1.1

Automated release via CI (npm trusted publishing, with provenance). Same 16-format extractor as 0.1.0; first CI-published, provenance-attested build.
