video_downloader.py correctly imports and uses secure_delete_file with await

guild.py correctly imports cleanup_downloads directly from file_ops.py
initialization.py now correctly imports cleanup_downloads from file_ops.py
cleanup.py now correctly imports cleanup_downloads from file_ops.py
utils/init.py correctly re-exports both functions
The circular import has been resolved by:

Having all files import directly from file_ops.py
Removing the re-export of cleanup_downloads from cleanup.py
Ensuring proper async/await usage throughout
