🐞 macOS Text Editing Keys Not Fully Working

### Description

I utilise the readline style text commands supported by macOS such as `Ctrl-f` and `Ctrl-b` to move forward and backwards a character, normally I would be able to use `Ctrl-Opt-f` and `Ctrl-Opt-b` to move forward and backward a whole word, inside of CodeEdit.app this does not work and I am met with the macOS `beep` sound.

If you could get this functionality setup and fixed I would definitely consider using this application for all coding that can'd be done in Xcode.

You can see the full list of supported commands [here](https://support.apple.com/en-gb/guide/pages/tanc0ffef022/mac) under _Move around within a document_.

### To Reproduce

1. open a file in the app
2. try to use readline commands that utilise Option
3. hear the `beep`

### Expected Behavior

The cursor should move forward or backward a word, or perform whichever other command you input via the keyboard.

### Version Information

CodeEdit: Version 0.3.2-alpha (43)
macOS: Version 15.1 Beta (24B5070a)
Xcode: Version 16.0 (16A242d)

首先在 macOS 上的 CodeEdit.app 中复现基于 Option 的 readline 命令，尤其是 Ctrl-Opt-f 和 Ctrl-Opt-b，并检查应用的键盘处理入口点。完成的标准是，列出的 macOS 文本编辑命令能够移动光标或执行其命令，而不会产生蜂鸣声。
