Update deployment process to handle machine learning dependencies

Create a dedicated script to install machine learning dependencies in the correct order, ensuring Cython is installed before packages that require it for compilation, and update documentation accordingly.

 ## 🔧 Step 1: Installazione Dipendenze
 
+⚠️ **IMPORTANTE**: Usare lo script dedicato per risolvere dipendenza Cython
+
 ```bash
 # SSH al server
 ssh user@ids.alfacom.it
 
-# Attiva venv
+# Esegui script installazione ML dependencies
-cd /opt/ids/python_ml
+cd /opt/ids
-source venv/bin/activate
+chmod +x deployment/install_ml_deps.sh
+./deployment/install_ml_deps.sh
 
-# Installa nuove librerie
+# Output atteso:
-pip install -r requirements.txt
+# ✅ Cython installato con successo
-
+# ✅ Dipendenze ML installate con successo
-# Verifica installazione
+# ✅ eif importato correttamente
-python -c "import xgboost; import eif; import joblib; print('✅ Dipendenze OK')"
+# ✅ TUTTO OK! Hybrid ML Detector pronto per l'uso
 ```
 
 **Dipendenze nuove**:
+- `Cython==3.0.5` - Build dependency per eif (installato per primo)
 - `xgboost==2.0.3` - Gradient Boosting per ensemble classifier
-- `eif==2.0.0` - Extended Isolation Forest
+- `eif==2.0.2` - Extended Isolation Forest
 - `joblib==1.3.2` - Model persistence
 
+**Perché lo script separato?**
+`eif` richiede Cython per compilare il codice durante l'installazione. Lo script installa Cython PRIMA, poi le altre dipendenze.
