cli.py

"""Command line interface for python-roborock.

The CLI supports both one-off commands and an interactive session mode. In session
mode, an asyncio event loop is created in a separate thread, allowing users to
interactively run commands that require async operations.

Typical CLI usage:
```
$ roborock login --email <email> [--password <password>]
$ roborock discover
$ roborock list-devices
$ roborock status --device_id <device_id>
```
...

Session mode usage:
```
$ roborock session
roborock> list-devices
...
roborock> status --device_id <device_id>
```
