[Bug] - nvim in terminal view doesn’t type SHIFT+<num> correctly.

### Short summary

Cannot access special symbols when using nvim in the integrated terminal.

### Affected version or release

v0.2.32

### Installation context

_No response_

### What happened?

I cannot type any of the special character associated with the number keys when I run nvim in the integrated terminal. All other shift modifiers seem to work. Affected symbols: `!@#%^&*()`. Could not reproduce in dedicated terminals or editors such as kitty and vscode.

### Steps to reproduce

1. Open a project
2. Open a terminal pane
3. Invoke nvim
4. Type SHIFT+<0-9>

### Expected behavior

Expect normal mapping of SHIFT+ keys.

### Additional context

- nvim v0.12.0
- MacOS Tahoe 26.5.1

首先，在 macOS 上使用 nvim，在集成终端中重现 SHIFT+0-9 输入，按照列出的步骤操作，并与专用终端进行比较。跟踪终端如何处理按下 Shift 时数字键产生的事件；完成标准是 !@#%^&*() 能在 nvim 中正确输入，同时不破坏其他 Shift 修饰键。
