BASS COLLIDER OS 5.1 FIX TEST2

This build addresses the exact tester failure:
/usr/local/bin/sclang: error while loading shared libraries: libncurses.so.5

On first install with Internet connected:
1. It tests whether sclang actually runs (not merely whether the file exists).
2. If the legacy Organelle sclang only lacks libncurses.so.5, it installs Debian Bookworm libncurses5.
3. If no usable SuperCollider runtime remains, it installs Bookworm SuperCollider packages.
4. It performs a headless sclang smoke test.
5. Reboot once, then launch Bass Collider.
