Input Handling Refactoring

• Combined imports from node:stream (PassThrough)
• Reduced redundant import statements

New Classes/Functions

Settings

• New editorMode setting added to persistent configuration
• Default mode is "emacs" for backward compatibility

Switching to vim mode:

$ claude
> vim
Editor mode set to vim. Use Escape key to toggle between INSERT and NORMAL modes.

Using vim navigation:

# In NORMAL mode:
- Press 'i' to enter INSERT mode and start typing
- Press 'Escape' to return to NORMAL mode
- Use 'hjkl' for navigation
- Use 'dd' to delete a line
- Use '.' to repeat the last edit

Switching back to emacs mode:

> vim
Editor mode set to emacs. Using standard emacs-style keybindings.

The vim mode implementation provides a familiar editing experience for vim users while maintaining full compatibility with the existing emacs-style keybindings. The mode preference persists across sessions, so users only need to switch once.
