             Summary: camel-jbang - TUI shell panel: add a scrollbar to indicate scrollback position
                 Key: CAMEL-23829
                 URL: https://issues.apache.org/jira/browse/CAMEL-23829
             Project: Camel
          Issue Type: Improvement
          Components: camel-jbang
            Reporter: Adriano Machado


The embedded JLine shell
  panel in the Camel TUI \(camel\-jbang, ShellPanel\) supports scrollback via Shift\+PageUp/PageDown and the mouse wheel, but renders no visual scrollbar. There is no affordance
  showing the current position within the scrollback history.

Other TUI tabs \(Log, Source viewer, Diagram, Configuration, History\) already render a vertical scrollbar using
  tamboui Scrollbar / ScrollbarState via a horizontal layout split \(content fill \+ 1\-column scrollbar\). The shell panel should follow the same pattern for
  consistency.

Acceptance: a vertical scrollbar appears on the shell panel reflecting scroll position when scrollback content exceeds the viewport.
