0e73226a59 refactor: Implement centralized extractor library to eliminate code duplication 
MAJOR ARCHITECTURE REFACTOR - Clean Study Folders

Problem Identified by User:
"My study folder is a mess, why? I want some order and real structure to develop
an insanely good engineering software that evolve with time."

- Every substudy was generating duplicate extractor code
- Study folders polluted with reusable library code (generated_extractors/, generated_hooks/)
- No code reuse across studies
- Not production-grade architecture

Solution - Centralized Library System:
Implemented smart library with signature-based deduplication:
- Core extractors in optimization_engine/extractors/
- Studies only store metadata (extractors_manifest.json)
- Clean separation: studies = data, core = code

Architecture:

BEFORE (BAD):
  studies/my_study/
    generated_extractors/           ❌ Code pollution!
      extract_displacement.py
      extract_von_mises_stress.py
    generated_hooks/                ❌ Code pollution!
    llm_workflow_config.json
    results.json

AFTER (GOOD):
  optimization_engine/extractors/   ✓ Core library
    extract_displacement.py
    extract_stress.py
    catalog.json

  studies/my_study/
    extractors_manifest.json        ✓ Just references!
    llm_workflow_config.json        ✓ Config
    optimization_results.json       ✓ Results

New Components:

1. ExtractorLibrary (extractor_library.py)
   - Signature-based deduplication
   - Centralized catalog (catalog.json)
   - Study manifest generation
   - Reusability across all studies

2. Updated ExtractorOrchestrator
   - Uses core library instead of per-study generation
   - Creates manifest instead of copying code
   - Backward compatible (legacy mode available)

3. Updated LLMOptimizationRunner
   - Removed generated_extractors/ directory creation
   - Removed generated_hooks/ directory creation
   - Uses core library exclusively

4. Updated Tests
   - Verifies extractors_manifest.json exists
   - Checks for clean study folder structure
   - All 18/18 checks pass

Results:

Study folders NOW ONLY contain:
✓ extractors_manifest.json - references to core library
✓ llm_workflow_config.json - study configuration
✓ optimization_results.json - optimization results
✓ optimization_history.json - trial history
✓ .db file - Optuna database

Core library contains:
✓ extract_displacement.py - reusable across ALL studies
✓ extract_von_mises_stress.py - reusable across ALL studies
✓ extract_mass.py - reusable across ALL studies
✓ catalog.json - tracks all extractors with signatures

Benefits:
- Clean, professional study folder structure
- Code reuse eliminates duplication
- Library grows over time, studies stay clean
- Production-grade architecture
- "Insanely good engineering software that evolves with time"

Testing:
E2E test passes with clean folder structure
- No generated_extractors/ pollution
- Manifest correctly references library
- Core library populated with reusable extractors
- Study folder professional and minimal

Documentation:
- Added comprehensive architecture doc (docs/ARCHITECTURE_REFACTOR_NOV17.md)
- Includes migration guide
- Documents future work (hooks library, versioning, CLI tools)

Next Steps:
- Apply same architecture to hooks library
- Add auto-generated documentation for library
- Implement versioning for reproducibility

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.

15c06f7b6c 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)

Known Gaps (Out of Scope for Task 1.2):
- LLMWorkflowAnalyzer Claude Code integration returns empty workflow
  (This is Phase 2.7 component work, not Task 1.2 integration)
- Manual mode (--config) not yet fully integrated
  (Task 1.2 focuses on LLM mode wiring only)

Test Results:
=============
[OK] PASSED: LLM Workflow Validation
[OK] PASSED: Interface Contracts
[OK] PASSED: LLMOptimizationRunner Initialization
[OK] PASSED: Error Handling
[OK] PASSED: Component Integration
