Moving it onto the title row put it on the wrong side of a boundary: that row
lives on WorkspaceTab, above the sub-tabs, so it is drawn over Cowork, Co4E,
Folder and GraphRAG too — a button offering to create a project in the corner of
a chat. The title label beside it already followed the sub-tab; the button did
not, because I added it to the row without adding it to that rule.
Both follow it now. check_project_screen walks the other four sub-tabs and fails
if the button shows on any of them.
23/23 checkers pass.
