                Adds the ITK (Integration Test Kit) agent module to the reactor.
                Enabled by itk/run_itk.sh (via test_suite/current.py) which
                fetches a2a-itk into itk/a2a-itk, providing the .proto sources
                the module needs at generate-sources time. Off by default so
                the standard reactor build works without an a2a-itk checkout.
