Audio Splitter 0.1.15

Added

Changed

Fixed

• PyInstaller build: bundle NumPy and lameenc binaries so stem separation no longer fails with No module named 'numpy.core.multiarray'
• Declare numpy as an explicit project dependency (used directly by audio_io.py)
• Remove stale torchaudio 1.x hidden imports (backend, io) that caused PyInstaller errors on torchaudio 2.x

Removed
