I've improved the way pywayfire finds sockets, it's now automatic, even if there are ENV issues.
will handle cases like:

export WAYFIRE_SOCKET=""  
export WAYFIRE_SOCKET="/wrong_path/to/socket_file" 

Maybe you dislike it because allow_manual_search=True is now default, but if you try using the wrong ENV, you’ll get how convenient this is

allow manual search should be False by default. The env var is always set if you have your environment properly set up.
