CNN v2: Change feature #6 from sin(10*x) to sin(20*y)
Update positional encoding to use vertical coordinate at higher frequency.
Changes:
- train_cnn_v2.py: sin10_x → sin20_y (computed from uv_y)
- cnn_v2_static.wgsl: sin10_x → sin20_y (computed from uv_y)
- index.html: sin10_x → sin20_y (STATIC_SHADER)
- CNN_V2.md: Update feature descriptions and examples
- CNN_V2_BINARY_FORMAT.md: Update static features documentation
Feature vector: [p0, p1, p2, p3, uv_x, uv_y, sin20_y, bias]
Rationale: Higher frequency (20 vs 10) + vertical axis provides better
spatial discrimination for position encoding.
