// src/editor/hook/export_edit.rs

// EditorHook: the console's /export action. Compiles the working entries in
// memory on a worker thread (under the one-cook-at-a-time guard), writes the
// named skinned mesh as `<name>.glb` beside the project's world file, and
// reports through the log sink and a toast.
