Option for a smaller banner in CLI output

Hi there!

First and foremost, thanks for the nice project! 🎉

I was wondering if it would be possible to implement a smaller banner option (perhaps via a command line flag or configuration file). For CLI apps, users would be greeted with the `jbundle` ASCII art banner, which IMHO is cool but takes up a lot of space. I believe that a simpler line like "Packaged with jbundle" could be a good alternative for certain scenarios.

Thanks for considering this! 😉

Cheerio!

Start by locating where the CLI banner is generated and where command-line flags or configuration are defined. Trace how normal CLI output is assembled, then make the smaller-banner choice produce the proposed one-line message while preserving the existing banner option; verify both output modes through the available CLI checks.
