- Delete all test_*.cpp, *.cmake helpers, MockCoordTrans.h and the gtest/strix
tooling from tests/: the only target (migration_tests) was guarded by
NOT RELEASE_BUILD, so nothing in tests/ compiles in this branch's
release build.
- Replace tests/CMakeLists.txt with a configure-only placeholder so the
unconditional ADD_SUBDIRECTORY(tests) from the root CMakeLists stays
resolvable without emitting the 'No migration test sources found'
warning or triggering the GTest FetchContent fallback.
- Scope new_docker_build.sh (1672 -> 694 lines) to this branch: keep the
prebuilt-image build/use/delete flow, .envrc/MIGRATE_PIPELINE_ROOT and
rti_license validation, the release-scope in-container cmake/make/ctest
and the Jenkins builder package production. Remove the GROUP1-11
target lists and options, viewer-only, grantlee/arcgis/codification
toggles, tests-only, integration-test and verify-rpm machinery.
