Research direction

This issue requests adding visible (LED) and verbal (Mission Planner) warnings when a fence is breached in Copter. The body is empty, but comments may provide context. Start by examining the existing fence code in libraries/AP Fence/AP Fence.cpp and AP Fence.h. Also review how LED warnings are handled in libraries/AP Notify and how Mission Planner receives messages via MAVLink. Check the issue comments for any discussed approach or maintainer feedback. Look for existing fence breach detection logic and where warnings are currently missing. A potential implementation would add calls to AP Notify for LED patterns and send MAVLink STATUSTEXT messages in the fence breach handler.
