Issue : Missing `__all__` in `awesome/__init__.py`

The `awesome/__init__.py` file is missing an `__all__` variable. This variable is used to define the public API of the `awesome` package. Without it, it's not clear which modules/classes/functions are intended to be used by external code, potentially leading to unexpected behavior if internal implementation details are accidentally relied upon. Add `__all__ = ["Awesome"]` to specify the Awesome class is part of public API.
