Subject: feat: Add PeakMeterEffect v2 for test_demo audio visualization

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
