feat: make OpenAdapt the canonical openadapt-flow launcher #16

	name: Noncanonical docs guard

	# docs.openadapt.ai is built and deployed by OpenAdaptAI/openadapt-ops from the
	# local openadapt-maintenance checkout. This repository only notifies that
	# pipeline through notify-docs.yml; it must never publish a competing Pages
	# artifact or claim the canonical custom domain.
