[BUG] Truncated shell command in ctrl+b background tasks

Preflight Checklist

What's Wrong?

When Claude runs a command in the background, it allows you to check the running command(s) with ctrl-B; but the listing doesn't reveal the full list of commands. Often it would be useful to see the full command list, and the display pane already takes up multiple lines of the screen; could it not list the full command, either by wrapping it, or by allowing me to scroll the text?

What Should Happen?

Show the full command with all its arguments and any redirections etc at the end of the command line.

Steps to Reproduce

1. Order or manipulate Claude Code into running a command line with more than some 66 characters in it in the background.
2. Attempt to see what it's doing by pressing ctrl-B and selecting this particular background task to see its "details".

Additional Information

If these are "details" I think it might be pertinent to note when exactly it was started, too, and perhaps how much user and system CPU it used.
