31 hoursfeat: Add PeakMeterEffect v2 for test_demo audio visualizationskal
Ports PeakMeterEffect to v2 Effect system with proper DAG routing. Red horizontal bar overlay displays audio_intensity for visual debugging of audio-visual synchronization. Changes: - New: src/effects/peak_meter_effect.{h,cc} - v2 implementation - Timeline: FlashEffect -> flash_out -> PeakMeterEffect -> sink - Build: Added to COMMON_GPU_EFFECTS and demo_effects.h - Test: Added to test_demo_effects.cc (9/9 effects pass) - Cleanup: Removed old disabled PeakMeterEffect code from test_demo.cc Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
