Ollama API Integration

The backend server manages models using the Ollama API:

• http://localhost:11434/api/tags - Installed models list
• http://localhost:11434/api/ps - Check running models
• http://localhost:11434/api/generate - Model load/unload and chat

Real-time Monitoring

• Real-time model status updates via SignalR Hub
• Background service for detecting model status changes
