FAST_LIO was renamed to duru_lio_ws to match the repo name; point the cd targets in the run scripts at the new path.
Vendor ikd-Tree directly instead of as a git submodule so cloning duru_lio_ws needs no --recursive/submodule-init step.
Clean up config/rviz assets for MID360S-only deployment and split run scripts by role (headless LIO via ssh, rviz-only on the local monitor, and combined run) so mapping.launch.py no longer needs config_file passed explicitly.
