Add comprehensive Windows support and documentation

Windows Support Package:
- PowerShell automated setup script (setup-windows.ps1)
  - Auto-detects KiCAD installation and version
  - Validates all prerequisites (Node.js, Python, pcbnew)
  - Installs dependencies automatically
  - Generates MCP configuration with platform-specific paths
  - Runs comprehensive diagnostic tests
- Windows troubleshooting guide (docs/WINDOWS_TROUBLESHOOTING.md)
- Platform comparison guide (docs/PLATFORM_GUIDE.md)

Code Enhancements:
- Enhanced Windows error diagnostics in Python interface
- Startup validation in TypeScript server
- Platform-specific error messages with troubleshooting hints
- Component library integration (153 KiCAD footprint libraries)
- Routing operations KiCAD 9.0 API compatibility fixes

Documentation Updates:
- Updated README with Windows automated setup
- Real-time collaboration workflow guide
- Library integration documentation
- JLCPCB integration planning
- Updated status to reflect Windows support
- Changelogs for Nov 1 and Nov 5 updates

Infrastructure:
- Added venv/ to .gitignore to prevent virtual env commits
