CRITICAL: Remove debug file I/O causing CPU glitches

PERFORMANCE FIX: Removed all debug file operations from audio callbacks
- File I/O operations (std::ofstream) in audio callbacks cause severe CPU spikes
- Was writing to /tmp/rhythm_steps_debug.log on every audio block
- This caused audio glitches and CPU overload symptoms

REMOVED:
- All std::ofstream debugFile operations from processBlock()
- All debugFile.close() calls from audio thread
- Debug logging from both main and transport timing calculations

RESULT: Should eliminate CPU glitches while preserving Steps mode fixes
