feat(cnn_v3): wire trained weights into CNNv3Effect + add timeline test sequence

- CNNv3Effect constructor loads ASSET_WEIGHTS_CNN_V3 via GetAsset on startup
- seq_compiler.py: CLASS_TO_HEADER supports full #include paths for cnn_v3/ classes
- timeline.seq: add cnn_v3_test sequence at 48s (GBufferEffect → CNNv3Effect)
- test_cnn_v3_parity: zero_weights test now explicitly uploads zeros to override asset

handoff(Gemini): CNNv3Effect ready; export weights to workspaces/main/weights/ and seek to 48s to test
