Add safe YOLO model env configurator

scripts/README.md

@@ -147,6 +147,30 @@ For Unraid/all-in-one deployments, place model files under
 `GEOINTEL_MODELS_PATH` so they appear in the container under `/app/models`, then
 set `YOLO_ENABLED=true` and `YOLO_MODEL_PATH=/app/models/<model>.pt`.
 
+Configure the Unraid/Tower env file from an existing local model without
+downloading weights or running inference:
+
+```bash
+python scripts/configure_yolo_model.py \
+  --models-dir /mnt/user/appdata/geointel/models \
+  --env-file /mnt/user/appdata/geointel/.env
+```
+
+If exactly one supported model file (`.pt`, `.onnx` or `.engine`) is present,
+apply the env update explicitly:
+
+```bash
+python scripts/configure_yolo_model.py \
+  --models-dir /mnt/user/appdata/geointel/models \
+  --env-file /mnt/user/appdata/geointel/.env \
+  --apply
+```
+
+The configurator refuses to proceed when no model exists or when multiple model
+files are present without `--model-file`. It writes only
+`GEOINTEL_INSTALL_AI=true`, `YOLO_ENABLED=true` and the mounted
+`YOLO_MODEL_PATH`.
