Add directory handling in git operations: support discarding, diffing, and viewing directories in untracked files. Prevent errors when staging or generating commit messages for directories.
Extract LoginModal into reusable component for Claude and Cursor CLI authentication. Add minimal mode to StandaloneShell for embedded use cases. Update Settings to use new LoginModal component.
