New 99-line test file included in main test/runtests.jl: - Tests LinearElastic material traits (supported_physics, required_field_types, required_state_variables) - Validates trait function existence and exports - Tests helper functions (is_stateful, get_state_variable_types, get_state_variable_symbols) - Verifies compositional design philosophy for state variables - Tests physics-to-field-type derivation Ensures material trait system works correctly for compositional material design.
