Unable to Connect to Localhost by Default When OLLAMA_HOST is Set to 0.0.0.0

[Tryanks]

I set the environment variable OLLAMA_HOST to 0.0.0.0:11434, allowing it to serve the local network. At the same time, I am running some local applications written in Python on the same machine. I noticed that I cannot directly use from ollama import chat; instead, I must first specify client = Client("http://localhost:11434") before I can use client.chat.

I suspect this is because the ollama-python library also reads the OLLAMA_HOST environment variable and uses it as the default access address.

A possible fix would be to add a special case for handling 0.0.0.0 in the _parse_host method.
