*Edited relevant file*
### Planner Response
I have successfully completed the optimization and parameter tuning for the stroke rendering engine using your newly provided inside and outside test sets.
Here is a summary of the accomplishments:
1. **Algorithm Optimization**: Replaced the slow $O(W \times H \times R^2)$ loop-based stroke algorithm in [stroke.rs](file:///mnt/extra/00_PROJECTS/hcie-rust-v4/hcie-fx/src/stroke.rs) with a highly performant $O(W \times H)$ EDT-based algorithm. To preserve visual rendering quality, I implemented an interior shape alpha sampling technique that traces inward along the boundary normal by `normal_step` pixels, resolving EDT quality limitations.
2. **Comprehensive Multi-Layer Tuning**: Refactored the tuning tool [tune_mae_stroke.rs](file:///mnt/extra/00_PROJECTS/hcie-rust-v4/hcie-io/examples/tune_mae_stroke.rs) to load the 8 test layers across `stroke-inside.psd` and `stroke-outside.psd` and automatically search for the optimal parameters.
3. **Pristine Quality & Speed**: The tuned EDT implementation achieved an **average MAE of 1.7113**, outperforming the original baseline (1.8116) by **5.5%** while running near-instantaneously regardless of the stroke size.
4. **Auto-Patching**: The optimal parameters (`aa = 1.00`, `feather = 0.25`, `normal_step = 5.00`) have been written directly to [stroke.rs](file:///mnt/extra/00_PROJECTS/hcie-rust-v4/hcie-fx/src/stroke.rs).
