* demo(turtlebot3): add FusionCore + icp_odometry feedback loop demo Adds a TurtleBot3 Gazebo Harmonic demo (ref issue #1418 Option A) where FusionCore (wheel + IMU UKF) and icp_odometry tighten each other in a feedback loop: FusionCore's stable odom frame serves as the scan-match initial guess via guess_frame_id, and the ICP result feeds back into FusionCore as a second velocity source. rtabmap SLAM consumes the ICP output for mapping/loop-closure. Nav2 uses /fusion/odom.
