feat: add advanced circuit generation and text-to-schematic conversion
5b00dbe 
- Add comprehensive text-to-schematic conversion system with YAML and simple text parsing
- Add advanced circuit generation tools for automated schematic creation
- Add intelligent component layout and positioning utilities with grid-based placement
- Add S-expression schematic generation system for native KiCad compatibility
- Add component utilities for symbol mapping and footprint management
- Add coordinate conversion utilities for accurate positioning
- Add pin mapping system for component connectivity
- Add symbol utilities for KiCad symbol library integration
- Add comprehensive test coverage for all circuit generation features

Key Features:
- Text-based circuit description parsing (YAML and simple formats)
- Automated component placement with conflict resolution
- Wire routing and connection generation
- Native KiCad S-expression format output
- Component library integration and symbol mapping
- Boundary validation and layout optimization
- Comprehensive error handling and validation

This establishes a powerful foundation for AI-assisted circuit design
and automated schematic generation from natural language descriptions.

version here is a little tricky. let's default to 20250220 which is the kicad 9.0 format. kicad will have backward compatibility for versions
