This module contains all detection business logic including:
- DetectionService: Main service for UI element detection
- Service Factory: Singleton pattern for DetectionService
- Image Utils: Shared image loading utilities
- OCR Handler: OCR-only processing
- Response Builder: Response formatting utilities

Architecture:
- RF-DETR: Detects generic UI elements (single class)
- CLIP: Classifies detected elements into 6 types
- OCR: Extracts text content
- BLIP: Generates visual descriptions
