feat(agent): add gns3-copilot AI assistant integration module

Integrate the gns3-copilot AI assistant module to provide intelligent
   automation and interaction capabilities for GNS3 network emulation.

   Key components:
   - AI agent framework with LLM integration (supports Qwen vision model)
   - GNS3 client library for project topology management
   - Extensive prompt templates for various network operation scenarios
   - Tool library for node creation, linking, configuration, and management
   - Support for English level assessment (A1-C2) and specialized personas
   - Network drawing and topology visualization tools
   - Linux device automation via Nornir/Telnetlib
   - Window controller for UI interaction

   Features:
   - Multi-modal AI agent with vision capabilities
   - Automated network topology deployment and configuration
   - Interactive node and drawing management
   - File-based project operations (read, write, list)
   - Specialized prompts for different scenarios and skill levels
   - Comprehensive tool set for network device management
