Chat sessions without a project were dropped from the mobile session tree because no registered project owned their directory. The sheet now partitions sessions like the desktop sidebar and shows Chats as a collapsible section above the project tree, with the same rows, swipe actions and paging; search results label them "Chats" instead of the raw directory name.
