Subject: feat: Multi-pass rendering architecture and effect stubs

Implements a post-processing pipeline using offscreen framebuffers. Adds stubs for MovingEllipse, ParticleSpray, GaussianBlur, Solarize, Distort, and ChromaAberration effects. Updates MainSequence to orchestrate the scene pass and post-processing chain.
