Streamlined and updated all training docs with new patch-based approach.
Changes:
- HOWTO.md: Updated training section with patch/full-image examples
- CNN_EFFECT.md: Streamlined training workflow, added detector info
- training/README.md: Complete rewrite with detector comparison table
New sections:
- Detector comparison (harris, fast, shi-tomasi, gradient)
- Practical examples for different use cases
- Tips for patch size and batch size selection
- Benefits of patch-based training

- Implement CoordConv2d custom layer accepting (x,y) patch center
- Split layer 0 weights: rgba_weights (9x mat4x4) + coord_weights (mat2x4)
- Add *_with_coord() functions to 3x3/5x5/7x7 convolution shaders
- Update training script to generate coordinate grid and export split weights
- Regenerate placeholder weights with new format
Size impact: +32B coord weights + ~100B shader code = +132B total
All 36 tests passing (100%)
handoff(Claude): CNN coordinate awareness implemented, ready for training
