Desktop: cycle sessions in most-recently-used (MRU) order, or a toggle-last-two-sessions shortcut

Feature request

In the desktop app, the session-cycling shortcuts (Ctrl+Tab / Ctrl+Shift+Tab) walk the sidebar top to bottom. With a dozen sessions open, bouncing between the two or three I'm actively working in means tabbing through everything in between each time.

Ask: cycle sessions in most-recently-used order — like macOS Cmd+Tab, or MRU tab switching in editors/browsers — or at minimum a shortcut that toggles between the two most recent sessions.

If changing the default is too disruptive, an opt-in setting (session cycling: sidebar order | MRU) would be fine.

Environment: Claude Code desktop app on macOS 26 (Tahoe), bundled engine 2.1.247.
