Switch run_command to a single-run execution model that streams stdout/stderr live while capturing both streams in memory using selectors. This guarantees that command errors (e.g. make install, pip, nix) always show full diagnostics without re-running commands or risking deadlocks. Add unit tests for preview mode, success execution, failure handling, and allow_failure behavior. Context: https://chatgpt.com/share/replace-with-this-conversation-link
