Add KeyEvent::W handler to delete word operation in delete.rs

Context

This issue was identified during review of PR #272:

• PR: Consolidate notebook editor state module #272
• Comment: Consolidate notebook editor state module #272 (comment)
• Requested by: @panarch

Description

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

For consistency with Vim behavior, where both dw and de are valid delete word operations, the delete.rs handler should also accept KeyEvent::W.

Files Affected

• core/src/state/notebook/inner_state/editor/normal_mode/delete.rs (line 50)

Expected Behavior

Both dw and de should perform delete word operations, consistent with change.rs implementation.
