Anto01 2eb73c5d25 fix: Parse LLM design variable bounds correctly and save workflow config ...

CRITICAL FIXES:

1. Parameter Range Parsing Bug
   - LLM returns bounds as [min, max] array, but code was looking for 'min'/'max' keys
   - This caused all parameters to default to 0-1 range instead of actual mm values
   - Example: "20 to 30 mm" was being used as 0.2-1.0mm instead of 20-30mm

2. Missing Workflow Documentation
   - Added automatic saving of LLM workflow config to output directory
   - Creates llm_workflow_config.json with complete optimization setup
   - Includes design variables, bounds, objectives, constraints, engineering features

Changes:
- optimization_engine/llm_optimization_runner.py:
  * Lines 205-211: Parse 'bounds' array from LLM output
  * Lines 80-84: Save workflow config JSON for transparency
  * Maintains backward compatibility with old 'min'/'max' format

Test Results:
BEFORE:
- beam_half_core_thickness: 0.27-0.95mm (WRONG!)
- beam_face_thickness: 0.07-0.73mm (WRONG!)

AFTER:
- beam_half_core_thickness: 20.16-28.16mm (CORRECT!)
- beam_face_thickness: 21.69-24.73mm (CORRECT!)

E2E test now passes with realistic parameter values and proper documentation.
