feat(graph): redesign toolbar — icons, team color, no system button overlap

- Toolbar moved to top-10 (below macOS system buttons)
- Lucide icons for all buttons (Tasks, Proc, Edges, Play/Pause, Zoom, Pin, Close)
- Toggle buttons show active state with highlight background
- Team name + alive indicator uses team color from config
- Grouped buttons in glass panels with backdrop-blur
- Removed raw text-only buttons (was: "−", "⊡", "+", "⊞ Pin", "✕")
