Layout

For correctness, simplicity and performance, we need to improve the logic to refresh the screen.

• Remove/move logic into a dedicated layer between State and Renderer
• Invalidate/repaint only the impacted line(s)/cells.
• Hotspots:

Sort by top of stack, same collapsed (when >= 5):
        unicode_segmentation::tables::grapheme::grapheme_category::h7c3f67445534791a  (in example)        329
        unicode_segmentation::grapheme::GraphemeCursor::next_boundary::he29d337853eeb707  (in example)        115
        _$LT$rustyline..tty..unix..PosixRenderer$u20$as$u20$rustyline..tty..Renderer$GT$::calculate_position::h27c3e32aa6d92973  (in example)        106
