This refactor replaces the custom event broadcasting implementation with the centralized goutils/events package across idlewatcher. The changes include simplifying the WakeEvent struct, removing manual SSE channel management, and adopting a cleaner event history pattern. The frontend JavaScript has been updated to work with the new event format.
