Replaces Triangle library with Gmsh as the default triangulation engine for adaptive isogrid generation. Gmsh's Frontal-Delaunay algorithm provides: - Better adaptive density response (concentric rings around holes) - Superior triangle quality (min angles 30-35° vs 25-30°) - Single-pass meshing with background size fields (vs iterative refinement) - More equilateral triangles → uniform rib widths, better manufacturability - Natural boundary conformance → cleaner frame edges Comparison results (mixed hole weights plate): - Min angle improvement: +5.1° (25.7° → 30.8°) - Density field accuracy: Excellent vs Poor - Visual quality: Concentric hole refinement vs random patterns Changes: - Updated src/brain/__main__.py to import triangulation_gmsh - Added gmsh>=4.11 to requirements.txt (Triangle kept as fallback) - Updated README and technical-spec.md - Added comparison script and test results Triangle library remains available as fallback option.
