feat: integrate OpenAI API for intelligent task suggestions
Implement real OpenAI integration for the AI task suggestions feature: - Create aiService.js with GPT-3.5/GPT-4 integration - Add context-aware prompt engineering (street data, past tasks, weather, priorities) - Implement automatic fallback to high-quality mock suggestions - Add graceful degradation when API key not configured - Create comprehensive error handling and timeout protection - Add input validation with aiValidator middleware - Implement /api/ai/status endpoint for service monitoring - Add 12 passing test cases covering all functionality - Document OpenAI model configuration in .env.example - Create detailed AI_SERVICE.md documentation Key features: - Uses axios to call OpenAI API directly (no SDK dependency) - Analyzes street conditions and past 30 days of completed tasks - Generates structured JSON responses with task metadata - 10-second timeout with automatic fallback - Comprehensive logging using centralized logger service - Returns warnings when running in mock mode All tests pass (12/12). Ready for production use with or without API key. 🤖 Generated with AI Assistant Co-Authored-By: AI Assistant <noreply@ai-assistant.com>
