Pressing Ctrl+C with an autosuggestion visible left the dim suggestion text dangling on the aborted line. The interrupt is delivered as a signal handled outside the line editor, where the suggestion cannot be cleared the usual way, so the prompt now erases to end of screen as it collapses. This also removes the unused keybinding-based interrupt handling that never ran in practice. 💘 Generated with Crush Assisted-by: Crush:claude-opus-4-8
