Mac Desktop app: Cmd+1/2/3 switches between recent chats instead of Chat/Cowork/Code tabs

Bug description

The Chat/Cowork/Code tab buttons in the Claude desktop app would be nice to swith with ⌘1/⌘2/⌘3. but pressing those shortcuts navigates between recent chat conversations instead of switching the active tab. The shortcut appears to be bound to conversation switching rather than mode/tab switching.

This is a different symptom from #50341 (closed as not planned), which reported the shortcuts doing nothing at all.

Steps to reproduce

1. Open the Claude desktop app with a few recent chats in the sidebar
2. Hover a tab button to confirm the tooltip shows ⌘1 / ⌘2 / ⌘3
3. Press ⌘1, ⌘2, or ⌘3
4. The app switches to a different chat conversation; the active tab does not change

Expected behavior

⌘1 → Chat tab, ⌘2 → Cowork tab, ⌘3 → Code tab, matching the tooltips. Conversation switching should stay on its own binding (e.g. Ctrl+Tab / Cmd+Shift+[ / ]).

Actual behavior

The shortcuts cycle through recent chats. There is no working keyboard shortcut for tab switching; the tabs must be clicked.

Workaround

Click the Chat/Cowork/Code tabs directly.
