refactor: complete removal of 'Effect' suffix from C++ class names

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
