New file: test/domains/continuum/test_helpers.jl Helper functions: - create_test_mesh_tet4(n) - generates n-element Tet4 mesh - create_test_kernel() - creates LinearElastic kernel - create_test_cache() - creates COOCache - setup_assembly_test(n) - complete setup in one call Purpose: - Reduce code duplication across test files - Provide consistent test data - Make tests more readable - Easy to extend for other element types Used by test_full_assembly.jl, test_compute_block.jl, etc.
