[D05] compare_clt_fea.py: Pipeline Integration

[Siddardth7]

Due: March 31 | Day 5 of 14

• Remove TODO stub from compare_clt_fea.py
• Call evaluate_laminate() for baseline [0/45/-45/90]s layup — capture deflection + σₓₓ
• Call generate_inp.py via Python (import or subprocess)
• Run CalculiX via subprocess.run(['ccx', 'fea/baseline'], check=True)
• Call parse_ccx_results.py — capture FEA deflection + σₓₓ
• Print CLT and FEA values side by side (no formatting yet, just raw values)

✅ Done when: python compare_clt_fea.py runs end-to-end and prints CLT + FEA values without crashing.
