Eliminate ~100 lines of duplicated code across effect subclasses by moving common resource initialization to the base Effect class. Most effects repeatedly created uniforms buffers, samplers, and dummy textures with identical configurations.
Changes:
- Add shared members to Effect: uniforms_buffer_, sampler_, dummy_texture_*
- Add helpers: init_uniforms_buffer(), create_*_sampler(), create_dummy_scene_texture()
- Add gpu_create_*_sampler() and gpu_create_dummy_scene_texture() to gpu.h
- Move HEADLESS_RETURN_IF_NULL to Effect constructor
- Update 7 effects to use base class helpers (Flash, Heptagon, Passthrough, Placeholder, GaussianBlur, Particles, PeakMeter)
Benefits: Improved consistency, easier maintenance, reduced binary size.

Effects now accept start/end time parameters and automatically passthrough
when inactive. Implements buffer chain integrity via compile-time validation.
- Effect base class: dispatch_render() checks time bounds, auto-passthroughs
1:1 input/output effects outside [start, end] interval
- seq_compiler.py: validates producer/consumer lifespan constraints for
multi-output effects, adds --validate flag, always validates before codegen
- Updated all 9 effect classes and test fixtures to pass start/end times
- check_all.sh: includes timeline validation step
- Tests: 34/34 passing, demo runs successfully

Update effect class definitions in headers and implementations to match
timeline.seq naming convention. All tests passing (34/34).
Classes renamed:
- PassthroughEffect → Passthrough
- GaussianBlurEffect → GaussianBlur
- PlaceholderEffect → Placeholder
- HeptagonEffect → Heptagon
- ParticlesEffect → Particles
- RotatingCubeEffect → RotatingCube
- Hybrid3DEffect → Hybrid3D
- FlashEffect → Flash
- PeakMeterEffect → PeakMeter

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
