Exit successfully on audio crash if SpringBoard scanned

Key insight: If Spring crashes on audio AFTER scanning SpringBoard,
the test should PASS. This proves:
✓ SpringBoard is a valid Spring archive
✓ Archive scanner can read it
✓ RmlUi conversion didn't break Spring compatibility

Audio crash is CI limitation, not SpringBoard bug. If scanning happened,
the smoke test achieved its goal.

Exit 0 immediately on audio crash + successful scan, skip LuaUI check.
