feat(cnn_v3): Phase 4 complete — CNNv3Effect C++ + FiLM uniform upload
- cnn_v3/src/cnn_v3_effect.{h,cc}: full Effect subclass with 5 compute
passes (enc0→enc1→bottleneck→dec1→dec0), shared weights storage buffer,
per-pass uniform buffers, set_film_params() API
- Fixed WGSL/C++ struct alignment: vec3u has align=16, so CnnV3Params4ch
is 64 bytes and CnnV3ParamsEnc1 is 96 bytes (not 48/80)
- Weight offsets computed as explicit formulas (e.g. 20*4*9+4) for clarity
- Registered in CMake, shaders.h/cc, demo_effects.h, test_demo_effects.cc
- 35/35 tests pass
handoff(Gemini): CNN v3 Phase 5 next — parity validation (Python ref vs WGSL)
