yumoqing ffdba55fd7 feat: add full 4-stem demucs mode with MIDI instrument replacement
- Support mode='full' in handle_demucs_separating config
- Full mode: 4-stem separation → basic-pitch MIDI → fluidsynth render → mix
- Each instrument gets correct GM instrument (drums=channel10, bass=34, other=1)
- 2-stem mode preserved as default for backward compatibility
- Uses run_full.py standalone script on GPU server via SSH
