Port automatic input layout alignment from hop-data-vault Merge Rows Plus into the core Merge Rows transform. When enabled (default), reference and compare streams are unioned before compare with null fill and reference-authoritative types. Strict identical-layout mode remains available via align_input_layouts=N. Also add TEST_FILTER support to integration-tests/scripts/run-tests.sh and run-tests-docker.sh so developers can run a subset of main*.hwf workflows (substring or glob, comma-separated) when debugging Docker integration tests.
