Subject: chore(src/gpu): remove stale cnn_v1/v2 artifacts and dead comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- demo_effects.h: drop commented-out cnn_v1/v2 includes (will be removed)
- gpu.cc: replace stale "V2:" migration comments with accurate descriptions
- effect.h, sequence.h: drop redundant #ifndef guards (kept #pragma once)

handoff(Gemini): stale comment cleanup in src/gpu/ — no logic changes
