nhance LLM usability with structured output and improved parsing

- Replace raw string return with structured JSON response containing scan results,                                                                                                                                                        
  open ports, service info, and performance metrics                                                                                                                                                                                       
- Add comprehensive error handling including timeout management                                                                                                                                                                           
- Implement active parsing of nmap output for key information extraction                                                                                                                                                                  
- Improve documentation to highlight LLM optimization                                                                                                                                                                                     
- Limit data exposure to prevent overwhelming the agent while maintaining utility                                                                                                                                                         
                                                                                                                                                                                                                                          
This change makes the nmap tool's output more predictable and actionable for AI agents,
