Function TestAltEnterInsertsNewline

internal/tui/tui_test.go:1530–1541

TestAltEnterInsertsNewline: Alt+Enter composes a multi-line prompt. The alt-flagged KeyEnter ("alt+enter") matches no textarea binding, so the flag must be stripped before forwarding or the key is a silent no-op and multi-line prompts can only be pasted.

// TestCtrlLClosesPopover: Ctrl+L clears the popover along with the prompt.
// Left open on stale suggestions, the next Enter would take the has-selection
// path and insert a ghost command into the freshly emptied prompt.
