The generated Makefile supports optional local workflow validation using
act. When act is installed and Docker is
available, pass WITH_ACT=1 to the test target:
make test WITH_ACT=1
This sets RUN_ACT_VALIDATION=1 for the pytest invocation, enabling the
act-based integration tests that run the generated CI workflow locally. Omitting
WITH_ACT (or setting it to 0) skips act validation; the rest of the test
suite runs unchanged.
