feat: Add example configuration file

This commit adds config/config.example.yaml with comprehensive configuration options for:
- Application settings and logging
- Protocol parameters (crypto, PUF, chaotic maps)
- AI/ML configuration
- Network and communication settings
- Entity-specific defaults
- Future features (GUI, database, API)
- Security and monitoring options

This provides a template for configuration management as outlined in CLAUDE.md.
