Major refactoring: replace material state cache with compositional
workspace using NamedTuple fields for better flexibility and zero-allocation.
- Rename MaterialStateCache to AssemblyMaterialWorkspace
- Change from M<:AbstractMaterialState to FieldType, StateType parameters
- Use AoS pattern: fields::Vector{FieldType} instead of separate σ, 𝔻 vectors
- Add zero-allocation field access via @generated functions
- Add extract_tangent! for type-stable zero-allocation tangent extraction
- Add get_tangent_vector, get_stress_vector helper functions
- Add @field_vector macro for compile-time field access
- Add get_stress, get_tangent, get_field accessor functions
- Update reset! to use create_zero_field and create_zero_state
- Update create_material_cache to use trait system for type inference
- Add backward compatibility alias create_assembly_workspace
- Add extensive documentation for zero-allocation usage patterns
