name: Slow Integration Tests

# The workflow will always run, but the actual tests will only execute when:
# - The workflow is triggered manually
# - The workflow is scheduled
# - The PR has the "run-slow-tests" label
# - The push is to a release branch
# - There are changes to relevant files.
# Note: If no conditions are met, the workflow will complete successfully without running tests
# to satisfy Branch Protection rules.
