facett-filedialog/tests/a11y.rs

//! **FC-4/FC-5 interaction-layer proof for facett-filedialog.** Before FC-4 the
//! whole listing was painted on a single `Sense::hover()` alloc — selection was a
//! mere `rect_filled` accent — so zero accesskit nodes existed: a robot driver /
//! screen reader / `egui_kittest` `get_by_label` could see *none* of the file
//! rows, let alone which one was selected. This renders a real [`FileDialog`] over
//! a known injected listing through `egui_kittest`, marks one row selected, and
//! asserts:
//!
//! * every file/dir row rode in as a labelled `Role::Button` node retrievable by
//!   its file name (egui's `SelectableLabel` maps to `accesskit::Role::Button`),
//!   and
//! * the *selected* row reports `Toggled::True` while an unselected row does not —
//!   the selection state is now real accessibility data, not just painted pixels.
//!
//! FC-5: the rows are keyed on the stable file *name* (the helper hashes `&e.name`,
//! not the loop index), so identity survives reorder/insert/delete.
