Summary
The new approach has two main parts:
Stable cursor tracking: amux remembers where the chat input prompt cursor is (the "stable cursor") and pins display there. During streaming, only cursor positions in the bottom input band are trusted; when idle, the full viewport is trusted. This replaces the blanket time-based suppression.
Hardware cursor promotion: the terminal cursor is promoted to a real tea.Cursor (hardware cursor) for native blink rendering, with awareness of overlays and toasts that might occlude it.
