CLI /usage Stats > Models tab is not keyboard or mouse accessible

Bug

In the /usage dialog, the Stats tab contains two sub-tabs: Overview and Models. The Models sub-tab cannot be accessed via keyboard navigation or mouse click — there is no way to switch to it from the UI.

Steps to reproduce

1. Run /usage in Claude Code
2. Click the Stats tab (or navigate to it)
3. Observe the two sub-tabs: Overview (selected) and Models
4. Attempt to click Models or use Tab/arrow keys to navigate to it — nothing happens

Expected behavior

The Models sub-tab should be reachable via mouse click or keyboard navigation (e.g. arrow keys or Tab), consistent with how the top-level tabs (Status / Config / Usage / Stats) work.

Actual behavior

Overview remains selected and Models is never reachable. The sub-tab appears to be rendered but has no interactive handler.

Environment

• Platform: Windows 11
• Shell: Claude Code CLI (terminal)
