fix(ux): exit YOLO before Shift+Tab or /mode preset switch

Ghost state bug: pressing Shift+Tab or /mode while YOLO was active left
session.yolo=true and settingsManager bypass ON even though mode changed.

- Shift+Tab handler calls s.toggleYolo() + settingsManager.toggleYOLO()
  before cycling to the next preset when YOLO is active
- handleModeCommand does the same before applying a named preset

This keeps yolo flag, status display ('SF — 🚀 YOLO'), and safe-git bypass
in sync with the actual running mode at all times.
