Improve large Copy/Paste text

### Describe the feature or problem you'd like to solve

Display first 1 or 2 lines whenc "Copy paste"

### Proposed solution

It'd be helpfull if Copilot CLi could show the first 1 or 2 lines when pasting large texts, so rather than

```
[Paste #1 - 133 lines]
```

show this:

```
Please generate a Monday report....
[Paste #1 - 132 lines]
```
