Mirrors the SO-101 leader arm's joint_states into the follower's controller topics.

Runs as an always-on daemon. Configure via snap set:

 snap set so101-teleop leader-topic=/leader/joint_states
 snap set so101-teleop jtc-topic=/follower/arm_trajectory_controller/joint_trajectory
 snap set so101-teleop ros-domain-id=0
 snap set so101-teleop rmw-implementation=rmw_fastrtps_cpp

snap install so101-bringup so101-teleop works together with no configuration. If so101-safety is also installed in mode=jtc, route the trajectory through its gate instead of straight at the controller:

 snap set so101-teleop jtc-topic=/safety/follower/arm_trajectory_in

Check status with snap services so101-teleop / snap logs so101-teleop.
