Plan Review UX: Make clear that there are top/bottom and page up/down keyboard commands

[dthyresson]

Summary

When reviewing a command one can scroll using arrow keys line by line.

White I didn't know is that there are top / bottom and page up / down keyboard shortcuts.

Turns out that on a Mac fn + left / right arrow will navigate to top or bottom of the plan and fn + up / down arrow will scroll by page.

Expected Behavior

Clearer keyboard shortcut help info to let user know keyboard nav options.

Actual Behavior

No hints given for nav, but other help is provided.

Steps to reproduce the issue

1. View an existing plan that is longer than a few pages.

Command Code Version

1.3.1

Operating System

macOS

Terminal/IDE

ghostty

Shell

zsh

Additional context

I did see this is documented however, but still could be helpful in the review UI as well.

Thanks @dthyresson will try to integrate shortcuts the best way possible.
