Greptile Summary

This PR refactors conversation list items in both ConversationList and Sidebar to use an absolutely-positioned overlay button (absolute inset-0) as the full-row click target, replacing the previous flex button that only covered the text area. Interactive siblings (drag handle, dropdown trigger) get relative z-10 so they paint above the overlay and receive pointer events first.

• ConversationList.tsx: The select button is converted to an absolute inset-0 overlay; content moves into an aria-hidden sibling div; the aria-label is enriched with message count and model count; the dropdown trigger gains relative z-10.
• Sidebar.tsx: The same overlay pattern is applied to both SortablePinnedItem (with the drag handle already getting relative z-10) and the inline conversation item inside the main conversation tree.

Confidence Score: 5/5

Safe to merge — changes are purely presentational/structural and don't touch data, routing, or state management logic.

All three click-target refactors follow the same pattern consistently: overlay button covers the row, interactive siblings (drag handle, dropdown trigger) are lifted with relative z-10 so they receive pointer events before the overlay. Event propagation and stacking-context behaviour are handled correctly throughout.

No files require special attention.

Important Files Changed

Filename	Overview
ui/src/components/ConversationList/ConversationList.tsx	Select button replaced with full-row overlay; aria-label enriched with message/model counts; dropdown trigger gets z-10 lift; logic is correct.
ui/src/components/Sidebar/Sidebar.tsx	Same overlay pattern applied to SortablePinnedItem and inline conversation rows; drag handle and dropdown triggers correctly promoted to z-10; no regressions found.
