[FEATURE] Android foldable (Galaxy Z Fold7): allow collapsing the sessions sidebar in the Code tab

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

On the Galaxy Z Fold7’s unfolded inner screen, the Code tab always shows the sessions list as a fixed left pane, and there’s no way to hide it. On a screen this size, the pane takes up a large share of the width while working in a session, especially when reading diffs or long output.

Expected: a toggle to collapse or expand the sessions pane, ideally with the state remembered across sessions and fold/unfold changes.

Current workaround: switching to the cover screen or using split-screen to force the single-pane layout, which defeats the point of using the larger inner display.

Device: Samsung Galaxy Z Fold7, Android 17, One UI 9, Claude app 1.261009.20
