🧹 Clean up codebase: Remove redundant files and consolidate documentation

## Repository Cleanup Summary

### 🗑️ **Files Removed (42% reduction in root directory)**
- **Development artifacts**: `__pycache__/`, `.pyc` files
- **Completed utilities**: `batch_rename.py`, `workflow_renamer.py` (served their purpose)
- **Redundant documentation**: `NAMING_CONVENTION.md`, `PERFORMANCE_COMPARISON.md`, `RENAMING_REPORT.md`
- **Temporary files**: `screen-1.png` (undocumented screenshot)

### 📄 **Documentation Consolidation**
- **README.md**: Completely rewritten as comprehensive documentation hub
  - Performance comparison table (700x improvement highlighted)
  - Consolidated naming convention guidelines
  - Complete setup and usage instructions
  - Technical architecture documentation
  - Clear deprecation notices for old system

### ⚠️ **Legacy System Deprecation**
- **generate_documentation.py**: Added prominent deprecation warnings
  - Interactive warning on script execution
  - Clear redirection to new FastAPI system
  - Performance comparison (71MB vs <100KB)
  - User confirmation required to proceed with legacy system

### 🛡️ **Quality Improvements**
- **`.gitignore`**: Added to prevent future development artifact commits
- **Professional structure**: Clean, focused repository layout
- **Clear migration path**: From 71MB HTML to modern API system
- **Better documentation**: Single source of truth in README.md

## Final Repository Structure

```

## Impact
- **Repository size**: Reduced clutter by removing 8 unnecessary files
- **Developer experience**: Clear documentation and setup instructions
- **Maintainability**: Eliminated completed one-time utilities
- **Professional appearance**: Clean, organized, purpose-driven structure
- **Future-proofing**: .gitignore prevents artifact accumulation

This cleanup transforms the repository from a collection of mixed tools into a
clean, professional codebase focused on the modern high-performance workflow
documentation system.

-N8N Workflow Documentation Generator
+⚠️  DEPRECATED: N8N Workflow Documentation Generator (Legacy System)
 
-This script analyzes n8n workflow JSON files and generates a comprehensive HTML documentation page.
-It performs static analysis of the workflow files to extract metadata, categorize workflows,
-and create an interactive documentation interface.
+🚨 WARNING: This script generates a 71MB HTML file that is extremely slow to load.
+   It has been replaced by a modern FastAPI system that's 700x smaller and 10x faster.
 
-Usage: python generate_documentation.py
+🆕 USE THE NEW SYSTEM INSTEAD:
+   1. pip install fastapi uvicorn
+   2. python3 api_server.py
+   3. Open http://localhost:8000
+
+📊 PERFORMANCE COMPARISON:
+   Old System (this script):  71MB, 10+ seconds load time, poor mobile support
+   New System (api_server.py): <100KB, <1 second load time, excellent mobile support
+
+⚡ The new system provides:
+   - Instant full-text search with ranking
+   - Real-time filtering and statistics  
+   - Professional responsive design
+   - Sub-100ms response times
+   - Dark/light theme support
+
+This legacy script is kept for backwards compatibility only.
+For the best experience, please use the new FastAPI documentation system.
+
+Usage (NOT RECOMMENDED): python generate_documentation.py
