Shift+Tab permission mode cycling drops 'don't ask' after leaving it

Bug description

When cycling through permission modes using Shift+Tab in the bottom status bar, the dontAsk mode gets permanently dropped from the rotation after cycling away from it.

Steps to reproduce

1. Start a Claude Code session with defaultMode: "dontAsk" in settings.json
2. Status bar shows: ►► don't ask on (shift+tab to cycle)
3. Press Shift+Tab to cycle to acceptEdits
4. Press Shift+Tab repeatedly — cycling is now stuck rotating through acceptEdits sub-states (accepted, pending, default)
5. dontAsk never reappears in the rotation

Expected behavior

Shift+Tab should cycle through all top-level permission modes in a loop (e.g. dontAsk → acceptEdits → plan → dontAsk → ...), regardless of which mode you started on.

Actual behavior

Once you leave dontAsk, it's excluded from the cycling array. You can only get back to it via /permissions or restarting the session.

Screenshot

Two side-by-side sessions — left shows don't ask on (initial state), right shows accept edits on (stuck, cannot cycle back):
