Previously Lua addon errors only logged to the log file. Now they display as red UI error text to the player (same as spell errors and game warnings), helping addon developers debug issues in real-time. Add LuaErrorCallback to LuaEngine, fire it from event handler and frame OnEvent pcall error paths. Wire the callback to GameHandler's addUIError in application.cpp.
