notebooks/production: fix view_production by running all notebooks; s… #7

	name: notebook-output-check

	# Hard gate: fail if any committed notebook still contains outputs or
	# execution counts. Contributors strip locally via the nbstripout clean
	# filter (see README "Notebook output stripping"); this verifies it.
