[Bug] Option+Delete (word deletion) not working in Ghostty

Option+Delete (for deleting word backwards) is not working within Claude Code. This keybinding works correctly in the regular Ghostty shell outside of Claude Code.

Environment:

• Claude Code version: 2.1.1 (Homebrew)
• Terminal: Ghostty
• OS: macOS (Darwin 25.0.0)
• Install method: Homebrew (/opt/homebrew/bin/claude)

Expected behavior:
Option+Delete should delete the word before the cursor (standard macOS text editing behavior).

Actual behavior:
The key combination does nothing or is being captured/ignored by Claude Code.

Workaround:
Alt+Backspace or Ctrl+W may work as alternatives.

Notes:

• Option+Left/Right (word navigation) works correctly after 2.1.0 fix
• Option+B/F also work for word navigation
• /terminal-setup is not available in Ghostty (hidden because Ghostty has "native support")
• The issue is specific to Claude Code - works fine in regular shell
