docs(chat): describe reply visibility per Replies After Collapse choice

The group-tree JSDoc and the ui-chat README stated that every reply stays outside whole-Turn folding and named only the collapse-timing setting. They now distinguish All replies from Final answer only and link the new setting.

 ## Summary
 
-Use this package to render a browser chat from recorded Session conversations, including historical images, localized actions, and restored scroll position. Work-details modes control reasoning previews and process visibility without hiding final answers; Verbose keeps completed-turn process rows visible. Local transcript and steering submissions appear immediately, remain in their original surface, and disappear atomically when authoritative Session records arrive, while queued submissions stay outside Chat. The package does not assemble or modify model requests.

 When Chat ends with an open Turn control and that Turn has no visible input, the first local transcript echo precedes the control. Other echoes remain at the flow tail. The control and echoes share one keyed list, so arrival of the control preserves the echo's mounted identity. Durable inputs replace their matching echoes in the same render.
