refactor: rewrite triangulation using Triangle library (constrained Delaunay + quality refinement)

Browse Source 
- Replace scipy.spatial.Delaunay with Shewchuk's Triangle (PSLG-based)
- Boundary conforming: PSLG constrains edges along inset contour + hole keepout rings
- Quality: min angle 25°, no slivers
- Per-triangle density-based area refinement (s_min=20, s_max=80)
- Clean boundary plotting (no more crooked v1 line resampling)
- Triangulation plot shows inset contour (red dashed) + keepout rings (orange dashed)
- Add sandbox2_brain_input.json geometry file
