Epitaxy Desktop Multi-Agent Rebuild

Description

April 14-15, 2026 Claude Code desktop app redesign shipping the features TestingCatalog had named 'Epitaxy'. First-class multi-agent IDE: parallel sessions in a sidebar, side chats (Command+;), integrated terminal / editor / diff viewer / preview pane, three view modes (Verbose, Normal, Summary), drag-and-drop layout, and Routines for headless automation. Not branded as Epitaxy but implements the multi-agent, multi-pane, coordinator-oriented design the leak and testers had described.
