par-term 0.49.0

//! UX.md MN3 seam: the menus follow the live bindings after a config apply
//! and after a keybinding change, and MN2 state reaches them.
//!
//! The native muda menu can only be built on the main thread, so these
//! tests drive the manager's real sync path for the in-app menu (which
//! rebuilds through the same model) and assert on the native menu's inputs
//! — the bindings and state `sync_menus` hands `MenuManager::rebuild` and
//! `apply_state` — plus the rebuild decision itself.
