…n events + bump v26.06.41 - ApplicationEventPublisher is now an injectable singleton bean (Spring ApplicationEventPublisher); inject it + await publisher.publish(event) to fire events into the context bus. - The event bus + @app_event_listener accept ANY object (not just ApplicationEvent subclasses); a listener whose param type matches (isinstance) receives it. Untyped/Any param still falls back to the catch-all ApplicationEvent (note: typing.Any is a class in 3.11+, excluded explicitly). Tests: tests/context/test_event_publisher.py (2). Gates: mypy --strict (619), ruff + format, full suite 3822 passed.
