feat(keymap): bind Ctrl+Backspace/Ctrl+Delete to word deletion

Add the de-facto standard terminal/editor hotkeys to the default key map:
- Ctrl+Backspace -> delete_word
- Ctrl+Delete -> delete_next_word

Previously only Alt+Backspace/Ctrl+w and Alt+Delete/Alt+d were bound,
which conflicts with muscle memory from readline, VS Code and other TUIs.

+- **Common word-deletion hotkeys**: Bind `Ctrl+Backspace` to [`TextArea::delete_word`] and `Ctrl+Delete` to [`TextArea::delete_next_word`] in the default key map, matching the de-facto terminal/editor convention (readline, VS Code, opencode).
