feat(03-backup): Scaleway backup S3 bucket foundation #81

	name: Verify Terraform Lock Files

	# Fails if any root's .terraform.lock.hcl is incomplete or stale for the
	# expected platforms (darwin_arm64 + linux_amd64). Re-runs `providers lock`
	# for both platforms and fails on any diff, so a lock missing EITHER
	# platform's hashes is caught regardless of the runner OS (a plain
	# `init -lockfile=readonly` on a linux runner would miss a darwin-only lock).
	# `providers lock` only talks to the provider registry, so no backend creds.
