Module dialog 

File dialogs as an ask: the app describes an Open, Save or folder dialog, the host shows the platform’s own, and the answer comes back as one {kind:"files", paths, tag} event (paths empty when cancelled).

Build a FileDialog and hand it to Ui::request_files from a view or Core::request_files between frames. The core cannot show a dialog, so it queues the ask; the windowed runner drains it and answers for you, while a host driving its own window drains Core::take_file_requests and answers with InputEvent::Files. One ask is out at a time: a second while one is unanswered is dropped, so a view that asks every frame until the answer lands asks once.

use kui_core::{Core, FileDialog, FileDialogMode, InputEvent};

let dialog = FileDialog::open()
    .multiple()
    .title("Add images")
    .filter("Images", &["png", "jpg"])
    .tag("import");

let mut core = Core::new();
assert!(core.request_files(dialog));

// A host without the runner: drain the ask, show the dialog, answer.
let asked = core.take_file_requests();
assert_eq!(asked[0].mode, FileDialogMode::Open);
let events = core.handle_input(InputEvent::Files(vec!["/tmp/a.png".into()]));
assert_eq!(events[0].kind(), Some("files"));
