New 93-line test file included in main test/runtests.jl: - Tests AbstractStateVariable type hierarchy - Validates state_variable_type trait (returns concrete types) - Validates default_symbol trait (returns symbols like :ε_p, :α, :κ, :d) - Tests concrete type instantiation (PlasticStrain, Backstress, etc.) - Tests NamedTuple usage with state variable symbols - Verifies trait consistency across all state variable types Ensures state variable system works correctly for material models.
