Subject: feat(sequence): Phase 3 - Port 3 effects to v2

- PassthroughEffectV2: simple copy effect
- GaussianBlurEffectV2: post-process with params
- HeptagonEffectV2: scene rendering effect

All use EffectV2 base with multi-input/output support.
Demonstrates single-pass, parameterized, and scene patterns.

Tests: 35/35 passing

handoff(Claude): Phase 3 complete, 3 v2 effects operational
