fix(multicursor): abandoned Visual selection does not move cursors #41670

Problem:
"v{motion}<Esc>" moves the primary cursor to the selection end, but the
other cursors snap back to their anchors unless follow-mode ("q=") is
on. The selection preview showed them at the selection end.

Solution:
Replay the abandoned selection at every cursor, not only in follow-mode.
An abandoned typed selection now always emits a "visual" CmdAtom.
