fe2ef9be6d feat: Implement Study Organization System (Organization v2.0) 
Reorganized simple_beam_optimization study and created templates for future
studies following best practices for clarity, chronology, and self-documentation.

## Study Reorganization (simple_beam_optimization)

**New Directory Structure**:
```
studies/simple_beam_optimization/
├── 1_setup/                    # Pre-optimization setup
│   ├── model/                  # Reference CAD/FEM model
│   └── benchmarking/           # Baseline validation results
├── 2_substudies/               # Optimization runs (numbered chronologically)
│   ├── 01_initial_exploration/
│   ├── 02_validation_3d_3trials/
│   ├── 03_validation_4d_3trials/
│   └── 04_full_optimization_50trials/
└── 3_reports/                  # Study-level analysis
    └── COMPREHENSIVE_BENCHMARK_RESULTS.md
```

**Key Changes**:
1. **Numbered Substudies**: 01_, 02_, 03_, 04_ indicate chronological order
2. **Reorganized Setup**: model/ and benchmarking/ moved to 1_setup/
3. **Centralized Reports**: Study-level docs moved to 3_reports/
4. **Substudy Documentation**: Each substudy has README.md explaining purpose/results

## Updated Metadata

**study_metadata.json** (v2.0):
- Tracks all 4 substudies with creation date, status, purpose
- Includes result summaries (best objective, feasible count)
- Documents new organization version

91e2d7a120 feat: Complete Phase 3.3 - Visualization & Model Cleanup System 
Implemented automated post-processing capabilities for optimization workflows,
including publication-quality visualization and intelligent model cleanup to
manage disk space.

## New Features

### 1. Automated Visualization System (optimization_engine/visualizer.py)

**Capabilities**:
- 6 plot types: convergence, design space, parallel coordinates, sensitivity,
  constraints, objectives
- Publication-quality output: PNG (300 DPI) + PDF (vector graphics)
- Auto-generated plot summary statistics
- Configurable output formats

**Plot Types**:
- Convergence: Objective vs trial number with running best
- Design Space: Parameter evolution colored by performance
- Parallel Coordinates: High-dimensional visualization
- Sensitivity Heatmap: Parameter correlation analysis
- Constraint Violations: Track constraint satisfaction
- Objective Breakdown: Multi-objective contributions

**Usage**:
```bash
# Standalone
python optimization_engine/visualizer.py substudy_dir png pdf

# Automatic (via config)
"post_processing": {"generate_plots": true, "plot_formats": ["png", "pdf"]}
```

### 2. Model Cleanup System (optimization_engine/model_cleanup.py)

**Purpose**: Reduce disk usage by deleting large CAD/FEM files from non-optimal trials

**Strategy**:
- Keep top-N best trials (configurable, default: 10)
- Delete large files: .prt, .sim, .fem, .op2, .f06, .dat, .bdf
- Preserve ALL results.json files (small, critical data)
- Dry-run mode for safety

**Usage**:
```bash
# Standalone
python optimization_engine/model_cleanup.py substudy_dir --keep-top-n 10

# Dry run (preview)
python optimization_engine/model_cleanup.py substudy_dir --dry-run

# Automatic (via config)
"post_processing": {"cleanup_models": true, "keep_top_n_models": 10}
```

**Typical Savings**: 50-90% disk space reduction

### 3. History Reconstruction Tool (optimization_engine/generate_history_from_trials.py)

**Purpose**: Generate history.json from older substudy formats

**Usage**:
```bash
python optimization_engine/generate_history_from_trials.py substudy_dir
```

## Configuration Integration

### JSON Configuration Format (NEW: post_processing section)

```json
{
  "optimization_settings": { ... },
  "post_processing": {
    "generate_plots": true,
    "plot_formats": ["png", "pdf"],
    "cleanup_models": true,
    "keep_top_n_models": 10,
    "cleanup_dry_run": false
  }
}
```

### Runner Integration (optimization_engine/runner.py:656-716)

Post-processing runs automatically after optimization completes:
- Generates plots using OptimizationVisualizer
- Runs model cleanup using ModelCleanup
- Handles exceptions gracefully with warnings
- Prints post-processing summary

## Documentation

### docs/PHASE_3_3_VISUALIZATION_AND_CLEANUP.md
Complete feature documentation:
- Feature overview and capabilities
- Configuration guide
- Plot type descriptions with use cases
- Benefits and examples
- Troubleshooting section
- Future enhancements

### docs/OPTUNA_DASHBOARD.md
Optuna dashboard integration guide:
- Quick start instructions
- Real-time monitoring during optimization
- Comparison: Optuna dashboard vs Atomizer matplotlib
- Recommendation: Use both (Optuna for monitoring, Atomizer for reports)

### docs/STUDY_ORGANIZATION.md (NEW)
Study directory organization guide:
- Current organization analysis
- Recommended structure with numbered substudies
- Migration guide (reorganize existing or apply to future)
- Best practices for study/substudy/trial levels
- Naming conventions
- Metadata format recommendations

## Testing & Validation

**Tested on**: simple_beam_optimization/full_optimization_50trials (50 trials)

**Results**:
- Generated 6 plots × 2 formats = 12 files successfully
- Plots saved to: studies/.../substudies/full_optimization_50trials/plots/
- All plot types working correctly
- Unicode display issue fixed (replaced ✓ with "SUCCESS:")

**Example Output**:
```

8b14f6e800 feat: Add robust NX expression import system for all expression types 
Major Enhancement:
- Implemented .exp file-based expression updates via NX journal scripts
- Fixes critical issue with feature-linked expressions (e.g., hole_count)
- Supports ALL NX expression types including binary-stored ones
- Full 4D design space validation completed successfully

New Components:
1. import_expressions.py - NX journal for .exp file import
   - Uses NXOpen.ExpressionCollection.ImportFromFile()
   - Replace mode overwrites existing values
   - Automatic model update and save
   - Comprehensive error handling

2. export_expressions.py - NX journal for .exp file export
   - Exports all expressions to text format
   - Used for unit detection and verification

3. Enhanced nx_updater.py
   - New update_expressions_via_import() method
   - Automatic unit detection from .exp export
   - Creates study-variable-only .exp files
   - Replaces fragile binary .prt editing

Technical Details:
- .exp Format: [Units]name=value (e.g., [MilliMeter]beam_length=5000)
- Unitless expressions: name=value (e.g., hole_count=10)
- Robustness: Native NX functionality, no regex failures
- Performance: < 1 second per update operation

Validation:
- Simple Beam Optimization study (4D design space)
  * beam_half_core_thickness: 10-40 mm
  * beam_face_thickness: 10-40 mm
  * holes_diameter: 150-450 mm
  * hole_count: 5-15 (integer)

Results:
✅ 3-trial validation completed successfully
✅ All 4 variables update correctly in all trials
✅ Mesh adaptation verified (hole_count: 6, 15, 11 → different mesh sizes)
✅ Trial 0: 5373 CQUAD4 elements (6 holes)
✅ Trial 1: 5158 CQUAD4 + 1 CTRIA3 (15 holes)
✅ Trial 2: 5318 CQUAD4 (11 holes)

Problem Solved:
- hole_count expression was not updating with binary .prt editing
- Expression stored in feature parameter, not accessible via text regex
- Binary format prevented reliable text-based updates

Solution:
- Use NX native expression import/export
- Works for ALL expressions (text and binary-stored)
- Automatic unit handling
- Model update integrated in journal

Documentation:
- New: docs/NX_EXPRESSION_IMPORT_SYSTEM.md (comprehensive guide)
- Updated: CHANGELOG.md with Phase 3.2 progress
