refactor(modes): collapse to Ask/Build; YOLO is a flag not a mode

- Remove 'plan' preset — ask covers discussion + planning, build covers execution
- Shift+Tab now cycles Ask ↔ Build (two stops, no awkward middle)
- YOLO (Ctrl+Y) forces Build mode if in Ask, then slams autonomous+deep+unrestricted
- Notify message shows 'switched to Build' when YOLO triggers a mode change
- YOLO off restores the pre-YOLO mode as before

Flow: Ask (user drives) → Build (SF drives) → Ctrl+Y (full send, no stops)
