Struct LineEndingsDialog 

pub struct LineEndingsDialog { /* private fields */ }

Line-endings dialog.

Holds a snapshot of the initial LineEndingConfig and a mutable pending copy that tracks the user’s edits. Emits DialogAction::ApplyLineEndingsLive on F2 / Enter on [Apply live], DialogAction::ApplyLineEndingsAndSave on F10 / Enter on [Apply + Save], and DialogOutcome::Close on Esc / Enter on [Cancel].

After emitting an Action, the dialog stays open — T17 wires the outer TuiApp to pop the stack once the action has been applied.
