feat: Complete working optimization pipeline with stress extraction

Browse Source 
COMPLETE PIPELINE VALIDATED:
- Stress extraction: 197.65 MPa (CTETRA elements) ✓
- Displacement extraction: 0.322 mm ✓
- Model parameter updates in .prt files ✓
- Optuna optimization with TPE sampler ✓
- Constraint handling (displacement < 1.0 mm) ✓
- Results saved to CSV/JSON ✓

Test Results (5 trials):
- All extractors working correctly
- Parameters updated successfully
- Constraints validated
- History and summary files generated

New Files:
- examples/test_stress_displacement_optimization.py
  Complete pipeline test with stress + displacement

- examples/test_displacement_optimization.py
  Displacement-only optimization test

- examples/run_optimization_real.py
  Full example with all extractors

- examples/check_op2.py
  OP2 diagnostic utility

- examples/bracket/optimization_config_stress_displacement.json
  Config: minimize stress, constrain displacement

- examples/bracket/optimization_config_displacement_only.json
  Config: minimize displacement only

Updated:
- .gitignore: Exclude NX output files and optimization results
- examples/bracket/optimization_config.json: Updated paths

Next Step: Integrate NX solver execution for real optimization
