Add KeyEvent::W support to delete word handler in delete.rs for Vim consistency

[coderabbitai]

Description

In core/src/state/notebook/inner_state/editor/normal_mode/delete.rs around line 50, the delete word handler only supports KeyEvent::E for DeleteWordEnd, while the equivalent handler in change.rs (line 35) supports both KeyEvent::E | KeyEvent::W.

In Vim, both dw and de are valid delete word operations. For consistency and better Vim compatibility, delete.rs should also handle KeyEvent::W.

Suggested Change

Update line 50 in delete.rs:

Key(KeyEvent::E | KeyEvent::W) => {
