fix: Stop passing design_vars to simulation_runner to match working 50-trial workflow **CRITICAL FIX**: FEM results were identical across trials **Root Cause**: The LLM runner was passing design_vars to simulation_runner(), which then passed them to NX Solver's expression_updates parameter. The solve journal tried to update hardcoded expression names (tip_thickness, support_angle) that don't exist in the beam model, causing the solver to ignore updates and use cached geometry. **Solution**: Match the working 50-trial optimization workflow: 1. model_updater() updates PRT file via NX import journal 2. Part file is closed/flushed to disk 3. simulation_runner() runs WITHOUT passing design_vars 4. NX solver loads SIM file, which references the updated PRT from disk 5. FEM regenerates with updated geometry automatically **Changes**: - llm_optimization_runner.py: Call simulation_runner() without arguments - run_optimization.py: Remove design_vars parameter from simulation_runner closure - import_expressions.py: Added theSession.Parts.CloseAll() to flush changes - test_phase_3_2_e2e.py: Fixed remaining variable name bugs **Test Results**: ✅ Trial 0: objective 7,315,679 ✅ Trial 1: objective 9,158.67 ✅ Trial 2: objective 7,655.28 FEM results are now DIFFERENT for each trial - optimization working correctly! **Remaining Issue**: LLM parsing "20 to 30 mm" as 0-1 range (separate fix needed)
