Replace the long scrolling DetailsIslandView with the new pinned layout: a
separated TaskHeaderBar (trash↔skull, gear), a DescriptionStepsCard (text⇄steps
toggle, Preview = composed prompt), and a pinned WorkConsole (Output/Actions/
Session tabs). The three components now bind to DetailsIslandViewModel; their
scaffolding sample VMs are removed. Drops the old inline sections + AgentStripView.
