improvement(chat): hide the agent-group viewport scrollbar

[waleedlatif1]

Summary

• Hide the scrollbar on the agent-group bounded viewport (the 110px narration window) using the existing scrollbar-hide utility
• The viewport is an ambient auto-following activity log — overflow is already signaled by the top/bottom fade edges, and wheel/trackpad scrolling (including detach/re-stick) still works

PR Summary

Low Risk
Single-class styling change on a chat UI scroll region with no logic or data-path changes.

Overview
Adds the existing scrollbar-hide utility to the BoundedViewport scroll container in agent-group.tsx (the 110px capped narration area inside expanded agent groups).

The native scrollbar is hidden so the log reads more like an ambient activity feed; overflow is still indicated by the top/bottom fade gradients, and wheel/trackpad scrolling plus auto-stick-to-bottom behavior are unchanged.

Greptile Summary

This PR hides the agent-group activity viewport scrollbar. The main changes are:

• Adds the existing scrollbar-hide utility to the bounded 110px log viewport.
• Keeps the existing overflow, padding, and fade-edge behavior unchanged.

Confidence Score: 5/5

This looks safe to merge after considering one small usability tradeoff.

• The added class already exists in the app stylesheet.
• The scroll APIs used by the viewport stay unchanged.
• The remaining concern is limited to losing the visible scrollbar thumb for manual navigation.

Important Files Changed
