FEAT: `app.run()` method for running uwsgi

### Describe the feature

When the code has this:

```python
if __name__ == '__main__':
app.run() # or maybe air.run()
```

Then it should launch the local server with default port of 8000 or something.

### Motivation

This is a semi-common pattern supplied by LLMs, even though it is a hallucination. So why not consider it a feature and implement it?
