New 384-line test file for Jacobian matrix computation: - Tests J = ∂x/∂ξ mapping between parametric and physical coordinates - Tests identity, scaled, and rotated element transformations - Tests 2D triangles and 3D tetrahedra - Tests physical derivatives: dN/dx = J⁻¹ · dN/dξ - Validates element quality detection (det(J) > 0) - Tests consistency with manual calculations - Validates type stability and zero-allocation performance - Tests both NTuple and Vector interfaces Comprehensive test for Jacobian computation essential for coordinate transformation and integration in FEM assembly.
