## Charge Stability Diagram, Coulomb Blockade, Pinch-off, and Turn-on models

Added the first batch of quantum device characterization models to the Control API:

* **Charge Stability Diagram**: segmentation, binary classification, and transition detection models
* **Coulomb Blockade**: classifiers and peak detectors for current measurements
* **Pinch-off**: classifier and parameter extractor for pinch-off curves
* **Turn-on**: classifier and threshold voltage extractor for turn-on measurements

```python
result = client.control.models.run(
    model="coulomb-blockade-peak-detector-v1",
    data=f,
)
```
