Use TransformerEngine for MXFP8 quantization #386

	# A maintainer-applied `run-ci*` label doubles as the "Approve and run"
	# decision for fork PRs from first-time contributors, on this and every later
	# push. Kept apart from pr-test.yml: tests run PR-world merge-ref code, while
	# approval must come from main's workflow definition and base-repo token
	# (`pull_request_target`). This job checks out nothing from the fork.
