Jukka Aho 8f198752ac feat(materials): Add LinearElastic material model with Tensors.jl ...

New file src/materials/linear_elastic.jl implementing Hooke's law:
- LinearElastic struct with Young's modulus E and Poisson's ratio ν
- Input validation: E > 0, -1 < ν < 0.5
- Helper functions: λ() and μ() compute Lamé parameters
- compute_stress() implements σ = λ·tr(ε)·I + 2μ·ε
- Tangent modulus: 𝔻 = λ·I⊗I + 2μ·��ˢʸᵐ
- Zero-allocation with SymmetricTensor types
- Simplified interface without state management
- 180 lines with comprehensive documentation
