Add a thread-safe deferred_invoke() API on WeakEventLoopReference that queues work onto the owning thread's event queue and wakes that thread via EventLoopManager hooks. This avoids calling wake() from foreign threads during teardown. Implement current_thread_handle()/wake_thread() in each backend and track per-thread data so handles are validated before waking: - Unix: wake via per-thread wake pipe - Windows: wake via thread wake event - macOS: wake via stored CFRunLoopRef - Qt: wake via event target or QEventLoop::wakeUp() - Android: wake via stored ALooper
