- launches/test_convert_direct.launch.tmpl: harvested working shared config
  (C/C++ Application + cuda-gdb 12.8; .tmpl suffix so Eclipse does not
  discover the template copy as a duplicate; setup.sh strips it on install)
- setup.sh: install launches/
- nsight_per_kernel_tests.md: modern Eclipse does not load the Nsight local
  'CUDA GDB Application' type - use C/C++ Application with cuda-gdb as GDB;
  shared-config save recipe; DP child-launch stepping caveat
- README: document launches/ templating
