Latest macOS build (Apple Silicon)

An unsigned build of main, for macOS 15 (Sequoia) and later on
Apple Silicon. Rebuilt on every push, so this is whatever main
currently says rather than a released version.

Built from commit 1ce215b.

Because it is unsigned, macOS refuses to open it until the
quarantine flag is cleared:

unzip OpenSCAD-macos15-arm64.zip
xattr -dr com.apple.quarantine OpenSCAD.app
open OpenSCAD.app

The command line binary is inside the bundle, at
OpenSCAD.app/Contents/MacOS/OpenSCAD.
