Errors when setting @click.option("--use_push_notifications", default=True)

When running the CLI and changing line 13 from @click.option("--use_push_notifications", default=False) to @click.option("--use_push_notifications", default=True) I would expect this to work.

The follow errors occur:

from .push_notification_listener import PushNotificationListener
ImportError: attempted relative import with no known parent package

The error occurs in hosts/cli/__main__.py at line 27 when trying to import PushNotificationListener. Start by examining the relative import structure and the condition that triggers this import. Check how the --use_push_notifications flag is handled and ensure the module path is correct when the flag is True. Run the CLI with the flag set to True to reproduce the error and verify the fix.
