Fix Docker container to run as host user and use host .ollama directory

This change prevents permission issues when using Ollama both locally and
in Docker by:
- Running container as host user (UID/GID) instead of root
- Mounting host's $HOME/.ollama directory using environment variables
- Setting HOME environment variable in container

This allows both the local binary and Docker container to share the same
model data without permission conflicts or duplication.
