Subject: [PATCH] fix(bridge): read window.TiptapEditor via Reflect.get, not
 function call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The extern 'fn get_module() -> TiptapEditorModule' was compiled by
wasm-bindgen to 'window.TiptapEditor()' — a function call. But
TiptapEditor is the IIFE module object, not a function, so this threw
'window.TiptapEditor is not a function'.

Replace with js_sys::Reflect::get(&window, "TiptapEditor") +
dyn_into, which reads the property without invoking it.

This bug predated the Vite 8 upgrade but only surfaced after the
EditorOptions fix let initialization progress further.
