ferridriver-cli 0.3.0

//! §2.9 Rule-9 integration tests: Dialog as a first-class event
//! handle accessible from scripts via `page.waitForEvent('dialog')`.
//!
//! The QuickJS binding returns a live [`ferridriver::dialog::Dialog`]
//! wrapper that exposes `type()` / `message()` / `defaultValue()` /
//! `accept(promptText?)` / `dismiss()`. These tests dispatch a
//! navigation that triggers `alert` / `confirm` / `prompt` and
//! observe both the read-only accessors and the side effects of
//! accept / dismiss on the page.
//!
//! Backend coverage:
//! * cdp-pipe / cdp-raw — full round-trip through
//!   `Page.javascriptDialogOpening` + `Page.handleJavaScriptDialog`.
//! * bidi — full round-trip through
//!   `browsingContext.userPromptOpened` + `browsingContext.handleUserPrompt`.
//! * webkit — the Obj-C host's `WKUIDelegate` decides the accept /
//!   dismiss before the event reaches Rust; the Dialog handle is
//!   still emitted so listeners can observe `type` / `message`, but
//!   calling `accept` / `dismiss` on the handle returns the typed
//!   error documented in `backend/webkit/mod.rs`. That branch is
//!   asserted explicitly rather than silently skipped.
