improved reliability and error handling for background notification actions by migrating to a top-level entry point for stable AOT callback resolution; implemented failure notifications to preserve undelivered reply text and surface technical errors; resolved a race condition that could resurrect dismissed notifications during silent re-renders; updated the Android manifest with the required broadcast receiver for notification actions; and refactored internal OCS methods to return detailed success/failure records for improved logging and field debugging.
