Jukka Aho 733c72b688 feat(materials): Add FiniteStrainPlasticity with multiplicative decomposition ...

New file src/materials/finite_strain_plasticity.jl implementing J2 plasticity for large deformations:
- FiniteStrainPlasticityState storing F_p (plastic deformation gradient), α_bar (backstress), κ
- FiniteStrainPlasticity struct with E, ν, σ_y, H parameters
- Hyperelastic stress response using Neo-Hookean
- Exponential map integration for plastic flow
- Pull-back/push-forward operations for intermediate configuration
- Consistent algorithmic tangent for Newton convergence
- 293 lines with comprehensive finite deformation theory
