Install the wait_robot_booted.py script - #615

PR Summary

Low Risk
Packaging-only change; adds one script to the install manifest with no effect on built libraries or launch behavior.

Overview
Installs scripts/wait_robot_booted.py alongside the other helper scripts in the non-Catkin install path (lib/${PROJECT_NAME}), so packaged builds expose it as an executable entry point (e.g. ros2 run ...).

No runtime or library code changes—only the CMake install(PROGRAMS ...) list is extended.
